The 6 Best JavaScript Frameworks to Use in 2022
As a web developer, you probably spend your days playing with JavaScript. And the chances are that you're not working with vanilla JavaScript because whoever tried building a complex UI knows that it is easier said than done. These days, vanilla JS has been superseded with JavaScript frameworks that provide you with the blueprints to build JavaScript-based client applications.
Frameworks have become prevalent in web development because they provide an easy way to create components and come with models and code separation systems.
As a frontend developer, you'll probably have to become familiar with a few of them. Many jobs require you to know your way around associated libraries and tools like React, Vue, Angular, or Svelte.
But with so many options to choose from, it might be hard to choose the best framework? In this article, you'll find a list of the most popular frameworks so you can make your own decision.
Here's what we'll cover:
What is a JavaScript framework?
JavaScript frameworks are tried and tested tools for building scalable web applications. They contain a collection of JavaScript code libraries that provide pre-written JS code for standard programming features and tasks.
Because of their functionalities, web frameworks often get confused with libraries, but they're different in scope.
A JavaScript library refers to packaged code, methods, and functions that can be reused and repurposed. On the other hand, a JavaScript framework defines the application design, can call on a library, and use code within it. It doesn't offer a single solution; instead, it gives you a set of blueprints for building web applications.
Frameworks have become a regular part of most JavaScript developers’ toolboxes. Instead of forcing you to build multiple times the same feature for different pages of your website, frameworks enable you to create components that can be reused numerous times on your web app.
Before modern frameworks existed, jQuery was the go-to library choice for developers who wanted to write JavaScript code without worrying about browser compatibility. All the functionalities you would use to develop your web app were abstracted into this lean and easy-to-learn library.
jQuery opened the door for new frontend tools, and modern frameworks like Backbone, Angular, and Ember appeared to provide a complete architecture for frontend application development.
What do JavaScript frameworks do?
A JavaScript framework guides developers on building complex applications faster and more efficiently by providing an ecosystem of tools that improves the developer experience. Frameworks enable you to add functionalities like testing and linting to ensure you're shipping error-free code.
Their structure dictates how you build your applications and enable the abstraction of different parts of your UIs into components that can be maintained and reused independently, simplifying the creation of highly dynamic, interactive applications.
In addition, frameworks also enable you to:
Manipulate your UI based on data
Solve common frontend challenges
Write maintainable and easy to read code
Reuse components common to other interfaces
Communicate ideas and patterns in a common language
Standardize UI elements such as color, buttons, and typography
JavaScript frameworks allow you to use domain-specific languages like TypeScript, JSX, and Handlebars to keep your code more straightforward and elegant when writing significant components. They also provide a better developer experience by integrating with tools that help write tests and debug code. Similarly, frameworks automate the installation, updates, and configuration of libraries, packages, and tools, making them significantly less convoluted and prone to errors than vanilla JavaScript.
Should you use one?
This might sound like a no-brainer. But to determine if you need a framework, ask yourself: Can I build this using vanilla JavaScript? The chances are that if your task is simple and doesn't need data fetching, two-way binding, complex routing, or app-like functionalities, using a framework is probably unnecessary.
Frameworks are packed with features, but none of them come for free. While they allow you to write more declarative code, you can end up with an extensive, unwieldy application that's computationally expensive to operate compared to regular JavaScript.
If your project is small and doesn't require interactive capabilities, a framework may not be necessary, and you would be better with vanilla JavaScript. That being said, some frameworks are better suited for smaller projects than others. In the end, you’ll need to assess your project first to see if employing one is a sound option.
The 6 most popular JavaScript frameworks
The line is thin between libraries and frameworks. In this list, we’ll include both libraries & frameworks.
There are more than 20 frameworks and 80 libraries available for developers to choose from, but here's are the six most popular you should know about in 2022:
React
Vue
Svelte
Angular
Ember
Backbone.js
Before we dive into each of these frameworks, here are the criteria I used to select them:
They're popular choices that have been around for a while and won't likely be discontinued
They have plenty of resources, tutorials, guides, and information for beginners
They have solid communities and solid documentation
Now, without further ado, let's see the best JavaScript frameworks in 2022 and beyond!
This list focuses on frontend frameworks. We couldn't recommend anything other than Node.js if you're looking for a back-end framework.
1. React
Created in 2013 by Facebook, React is the most used library according to the State of JavaScript 2021 survey. React is not technically a framework; it's a library for UI components, but it's seen colloquially as a framework, so I'll refer to it as so.
If you're looking for a React framework, you should have a look at Next.js.
React.js provides fast UIs for interactive apps which use data efficiently by instantly applying changes to elements rather than updating all occurrences at once as other libraries do. It also supports incremental use with the virtual DOM (document object model) to make fast updates to web page content. React also uses JSX, a domain-specific interface created by the same team.
Features
React components: React divides your page into multiple components. Each component is part of the UI and has its own logic and design, making them more accessible and faster to reuse.
Virtual DOM: The virtual document object model presents data in a tree structure. It also divides data into modules containing a node for each independent UI element present in the document. This ensures that when you reload a page, it only refreshes one part of it rather than the whole website.
JSX: JavaScript XML is an HTML-like syntax processed into JavaScript calls that enables developers to embed JavaScript objects inside HTML elements.
Declarative UI: JSX's HTML-style syntax allows you to control flow and state in your application by deciding how your component should look like.
2. Vue.js
Vue was created in 2014 by Evan You, a former Google employee. It aims to be a framework that combines the best features of Angular and React. Vue retains Angular's template syntax and React's data binding, props, and component-based approach.
Vue has a gentle learning curve. It allows developers with knowledge of HTML, CSS, and JavaScript to create enterprise-grade SPAs and cross-platform applications and integrate them into new or already existing projects using HTML or JSX.
Features
Animated transitions: Vue provides various ways to apply transition effects to HTML elements when adding or updating them from the DOM. You can also integrate third-party animation libraries for even more interactivity.
Templates: Vue provides HTML templates that bind the DOM with Vue's instance data. It compiles templates into the virtual DOM as HTML that can be parsed and rendered by all browsers.
Vue routing: Routing allows users to switch between pages without refreshing the page, making navigation easier and faster.
Directives: Directives are instructions that bind themselves to a property on a Vue instance. They enable VueJS to manipulate the visual part of your application to change what the user sees in front of it.
3. Svelte
Created by Rich Harris in 2016, Svelte.js is an open-source JavaScript framework that simplifies the creation of fast, static web apps by turning raw code into sleek and interactive user interfaces. Like React, Svelte is not precisely a framework; it's a compiler-as-a-framework that turns Svelte code into vanilla JavaScript to achieve faster performance than React or Vue.
/notice If you’re looking for a Svelte framework, you should look at SvelteKit.
Svelte compiles code into small, independent JavaScript modules, ensuring that the browser does as little work as possible, resulting in a faster loading time.
Features
No virtual DOM: Svelte works directly on the code without a DOM, and it moves most of the code processing to the compilation stage, achieving faster speeds than other frameworks.
Reactivity: Svelte converts components into DOM operations, reacting to data changes on its own and rendering changes as JavaScript code.
Requires less code: Svelte requires fewer lines of code than React and Vue, reducing the number of time developers spend writing code.
Modular CSS: Svelte ensures design consistency across pages and applications by scoping styles and generating unique class names.
4. Angular.js
Created by Google in 2010, Angular is a component-based framework. It offers developers a collection of integrated libraries and tools to develop, test, and update their code. This makes it a robust option for building and deploying web applications.
Angular combines declarative templates, dependency injection, solid end-to-end tooling, and an integrated set of best practices to solve development challenges.
Features
Two-Way Data Binding: Angular's two-way binding represents the model layer, so if you change the model, users can see changes in the view model automatically, decreasing development time.
Dependency injection: This programming paradigm allows classes, components, and modules to work interdependently while maintaining code consistency, reducing the frequency with which the class changes.
MVC architecture: This type of architecture isolates the application logic from the UI layer, supporting separation of concerns and saving you coding time.
5. Ember
Created in 2011 by Yehuda Katz, Ember is an MVC (Model-view-Controller ) framework that developers can use to develop both desktop and mobile applications and single-page applications.
Ember.js provides a new binding syntax using the HTMLBars template engine, a superset of the Handlebars templating engine that automatically updates any relevant data changes.
Features
Handlebars syntax: Handlebars is a templating language. It uses a template and an input object to generate HTML or other text formats. Handlebars templates look like a regular text with embedded expressions that use the handlebar syntax “{{}}”.
Ember Inspector tool: This tool enables developers to inspect their Ember code, see the state of a running Ember app, and debug applications quickly.
Ember-simple-auth: This feature enables you to manage authentication and authorization. It abstracts common patterns and integrates with other security addons for better authentication.
Application initializers: Application initialization runs your application as it boots and configures your application's dependency injection.
6. Backbone.js
Created by Jeremy Ashkenas in 2010, BackboneJS is an event-driven, minimalist JavaScript framework that allows you to develop and structure your client-side applications in a web browser. It offers an MVC framework that abstracts data into models; it binds these models using events that enables developers to build fluid user interfaces (UI) with less code.
When handling the DOM, Backbone.js adopts an imperative programming style that describes how to get what you want, contrasting with other frameworks’ declarative programming style.
Features
JavaScript functions: Functions in Backbone act as the building blocks of your JavaScript application and provide models with key-value binding and custom events.
Open source: Backbone is a free, open-source project with more than 100 free libraries to choose from.
Enables cross-platform development: Backbone enables developers to create applications that work on different browsers and devices.
Up and coming frameworks worth a look
We've explored the most popular JavaScript frameworks, but some newer frameworks are worth mentioning. Here they are:
Redwood.js
Created in 2020, Redwood is an opinionated full-stack framework that provides a standardized workflow and can deploy your application with a simple git push command. It takes control of the data side of your application and has a strong separation of concerns for both frontend and backend.
Features
Opinionated framework: Redwood wants you to build web applications using Jamstack-based tooling. It offers developers a default way of formatting code, organizing files, and using Webpack and Babel.
Serverless functions: Redwood leverages a GraphQL API with serverless backend functions running on Amazon Lambda. The main logic in Redwood is written as services that represent an API endpoint.
Built on React: Redwood shouldn't be hard to master if you already know React. It builds on top of React's development workflow to provide developers with a familiar way of building web applications.
Services layer: Redwood abstracts all your business logic into a services layer. This layer can be accessed via GraphQL APIs and serverless functions.
Remix
Created in 2020 by Michael Jackson and Ryan Florence, Remix has grown in popularity over the last two years. The idea behind Remix is that everything is server-side rendered (SSR). Data is rendered on the server and served to the client-side using as little JavaScript as possible.
Features
Progressive enhancement: Remix does SSR by default, but when JavaScript is not available, visitors don't get a blank page; instead, they get the same HTML document with a raw HTML experience.
Built-in forms: Despite being a JavaScript framework, Remix can also use AJAX to enable form submission without reloading the page.
Nested pages: Pages inside a route folder are nested in the route rather than being separate; you can embed components into your parent page, resulting in fewer errors and faster loading time.
Conclusion
Let's rewind for a minute. So, what is a JavaScript framework? Frameworks are blueprints that simplify web development. They provide you with libraries, documentation, and resources that you can use to write elegant, performant digital experiences.
As an aspiring frontend developer, you may be feeling a little overwhelmed by the number of different frameworks to choose from, but don't worry. You can start by learning one or two and gradually add more as you become more comfortable.
However, before you choose one, ask yourself these questions:
Do I need a framework?
Is the learning curve too steep?
Are the framework's features what I need?
Will the framework integrate well with my workflow?
What problems am I trying to solve with a framework?
If you don't have any experience with frameworks yet, now is the time to start learning. With so many companies using them as part of their standard tooling, having skills in one or more frameworks will give you an edge.
Just don't forget to have fun while you're at it.
