 Best Front End JavaScript Frameworks to Learn in 2021

Do you want to know which are the best JavaScript libraries and frameworks used for front-end development and their key features? Continue reading!

1. Angular

Angular is a front-end JavaScript framework for building web applications. It is a Google-created and maintained open-source JavaScript platform. It was first released in 2010.  It is a JavaScript platform that includes all of the tools that a modern front-end developer needs for a front-end framework.

Best Features 

  • Angular allows you to create native and web applications on both desktop and mobile platforms, and it’s especially well-suited to enterprise web applications.
  • Angular also adheres to the MVC (Model-View-Controller) architectural pattern, giving you control over UI components and behaviors. You can manipulate DOM attributes in Angular to meet your needs.
  • Two-way data binding, Angular CLI, directives, built-in dependency injection, virtual scrolling, and other notable features have made the framework extremely common among developers.

  • Microsoft
  • YouTube

 Drawbacks of angular 

It has a steep learning curve because one must first learn some extra items like TypeScript and RxJS before being fluent with angular. Compared to other frameworks, the build bundle size is enormous, which has a massive impact on load times.

2. Vue.js

Vue.js, or Vue, is an open-source JavaScript platform for creating interactive user interfaces.  It is an open-source progressive JavaScript platform developed in 2014. It has been rewritten and fine-tuned to become a fantastic single-page application.

Best Features

  • Components, models, transformations, and two-way data binding, and an emphasis on reactivity are among its features. 
  • Vue comes with a dedicated library for managing applications. We can easily combine Vue with existing projects and other JS libraries because it is a progressive platform.
  • It’s also an MVVM (Model-View-View-Model) platform, with the core library focusing solely on the view layer. 
  • The system also supports declarative rendering and part composition. 
  • Other notable Vue features include event handling, templates and directives, the Vue.js CLI, modules, transitions, reactivity focus, and many more.

 Top Companies using Vue

  • Stack Overflow
  • GitLab
  • Adobe

 Drawbacks of Vue 

A significant drawback of Vue is that it isn’t as stable as Angular and can’t be used to build advanced front-end projects. Also, working with tools like external stylesheets, fonts, and images can be a nightmare for a novice.

3. Svelte

Svelte is an open-source front-end JavaScript project written in TypeScript, created by Rich Harris.

Svelte compiles the code to pure JS and creates its compiler to translate apps into ideal JavaScript at build time rather than at runtime like other frameworks do.

Best Features

  • It has a simple and easy-to-understand syntax.
  • When the program is updating the DOM, it generally does not inject any overhead code to run. As a result, web apps built with Svelte are typically faster than those made with other frameworks.
  • Svelte has many notable features, including improved speed and performance, less code, no virtual DOM, and more.
  • It doesn’t have any complicated management libraries and provides better performance.

Top Companies using Svelte

  • Codustry
  • Screeb
  • Kontist
  • OmniaWrite

Drawbacks of Svelte 

Svelte’s main disadvantage is that it is still relatively new, so it lacks the community support of Angular, Vue, or React. Furthermore, jobs that require Svelte as a skill are uncommon.

4. Next.js

Next.js is a free and open-source front-end platform. It is a React-based framework that is very common among developers due to its server-side renderability.

It enables you to build Jamstack and server-based applications while adhering to best development practices.

Next.js, on the other hand, mainly supported CSS and styled JSX, as well as other technologies.

Best Features 

  • It is also written in TypeScript, allowing JavaScript modules and React components to be dynamically imported.
  • Next.js has several valuable features, including automated code-splitting, automatic routing, SEO support, prefetching, and more.
  • It also includes a static export function that allows you to export a fully static site from the application.
  • Redirect support, gradual static regeneration, and several other new features and functionalities have been released in the current version of Next.js.

Top Companies using Next.js

 It is used by companies like 

  • Netflix
  • Uber
  • Starbucks
  • Github 
  • Avocode etc.

Drawbacks of Next.js 

Even though NextJS is rapidly evolving and adding new functionality, it still has some drawbacks. Since Next.js doesn’t have many built-in front pages, you’ll have to build the entire front-end layer from scratch. You can only use NextJS’s file-based router; you can’t change the way it handles routes.

5. React

In the world of JavaScript, React is unquestionably the popular front-end javascript framework. This JavaScript framework takes a reactive approach to front-end web creation and incorporates several new concepts.

React is a UI component framework that permits integration with other JavaScript libraries to build reusable UI components.

Best Features 

  • It can create apps for any type of user interface, including web, desktop, and others, and it is highly recommended for creating SPAs (Single Page Applications) and business applications.
  • React employs JSX, an XML-style syntax that incorporates JavaScript and HTML. It’s not a templating language; it’s JavaScript in its purest form.
  • It combines the following features: reusable modules, state, and view synchronization, and a routing and template framework.
  • It also follows the MVC model and includes features such as One-way Data Binding, Virtual DOM, Event Handling, and more.

Top Companies using React 

  • Facebook 
  • WhatsApp 
  • Instagram
  • Yahoo mail

Drawbacks of React 

  • The disadvantage of using React is that building massive, complex web apps with react can quickly turn into a nightmare if you have not carefully planned your code structure.
  • Another disadvantage is that React only allows data to flow in one direction, which means that only parent components can transfer data to their children, not the other way around.

6. Ember

Ember is one of the oldest front-end JavaScript frameworks.

It is an open-source JavaScript project created and published in 2011. It was formerly known as SproutCore 2.0 before being renamed Ember.js.

Best Features

  • Ember.js is a web platform that follows the MVC (Model-View-Controller) design pattern, which can be used to create mobile and desktop applications.
  • It also considers HTML and CSS to be the foundation of its development model, and its backend architecture allows you to write advanced HTML tags.
  • It comes with templates for quickly creating simple pages and dynamically loading content using components and helpers.
  • Ember.js includes a separate data layer, models or handlebars, a built-in testing environment, and a slew of other features and functions.
  • The Glimmer rendering engine is included, which allows you to render DOM elements from the template.
  • Ember has an excellent build method called Ember CLI that many other SPA frameworks have borrowed. The command-line interface helps you to run tests in the browser, auto-reload components, and quickly restore, among other things.

Top Companies using Ember 

  • Apple,
  • Microsoft, 
  • LinkedIn, 
  • Netflix

Drawbacks of Ember

Complications with swift processing changes, smaller communities, and outdated tutorials on the web are all disadvantages of Ember. It’s also the most substantial of the frameworks.

Conclusion

Working as a front-end developer gives you many choices, so knowing which JS libraries and frameworks are best for which scenarios is crucial.

Frontend JavaScript frameworks have far more than the ability to create single-page applications; they also make our codebase far simpler to manage by offering that abstract away a lot of code and prevent duplication. Conditional rendering, conditional styling, the ability to emit custom events, and a central datastore are all included in its features.

In general, any framework can be used to build a JavaScript solution. It’s best to choose wisely, but when it comes to time and performance. We have compiled a list of the most common and recommended JavaScript frameworks for the year 2021, based on various important factors in this article.
