Top Front-End JavaScript Frameworks to Use in 2021

Technology has made the world better, faster, and more accessible. And it has a lot to do with a myriad of programming languages available today. There’s a constant battle going on among all of them. Who’s going to win - this is the penultimate question. The biggest reason behind this battle is user experience.

User experience tops the charts above anything else. Hence, it all boils down to what you display to your users. Yet, for a better user experience, developers need powerful frameworks for the front-end. Despite such a huge competition, JavaScript has emerged as the most popular programming language for many years now. The fundamental reason for the success of JavaScript is its versatility and flexibility.

What’s more, there is competition even for which JavaScript framework is better. Angular, React, and Vue still remains the top three contenders for JavaScript frameworks. Till 2016, only two competitors vying for the top spot - Angular and React. Vue came in to give these two a reality check on the web development scene. Third Rock Techkno covered an Infographic describing all the necessary information you need to make the right choice.

Hundreds of JavaScript frameworks and libraries are available for the developers to choose from for both client-side and server-side projects. If you find it difficult to choose a framework, you can also hire a dedicated web developer from us to ease the decision-making process.

While you contemplate the pros and cons of each framework, check out this list of top JavaScript Frameworks to watch out for in 2021:

Top Front-End JavaScript Frameworks to Use in 2021:

Angular

Angular js Top Front-End JavaScript Frameworks

After its launch in 2010 as AngularJS, this framework has undergone many upgrades in response to the changing trends in the development industry. AngularJS became Angular 2 with its first upgrade in 2016, and Angular 9 saw its release in February 2020.

Owing to its versatile features and component-based structure, this framework developed by Google comfortably sits at the top of the list of preferred JavaScript frameworks. Since Angular apps work on the TypeScript language, developers find it easier to identify and eliminate errors while writing the code or performing maintenance tasks.

Angular is the first choice of app developers for building single-page applications for both mobile and desktop.

The Good

  • The basic concept of Angular was to create a balancing effect between increased technology demands and conventional methods.
  • Its real-time sync with two-way data binding makes Angular a top choice. Developers can see any changes instantly on the model and view.
  • The dependency injection makes it easier to manage and reuse the components.

The Not-so-good

  • Being a dynamic solution, Angular offers a lot of ways to carry out a task. While this can make the learning curve difficult, the massive support community makes it easier.
  • Dynamic apps usually have a complex structure, which sometimes affects their performance. But it can be fixed by Angular’s code optimization feature.

When to Use Angular:

Angular is best for creating powerful and dynamic web applications. It offers two-way data binding, which means that any changes to the data automatically propagate to the views without reloading the page. Hence, Angular offers the best option for enterprise-level or dynamic web apps.

When Not to Use Angular:

If you are building an application with a small scope, you may not want to use an extensive framework like Angular. Since it's a frontend solution, Angular is not the right choice. For smaller projects, you can use smaller frameworks with simpler syntax and fewer complexities.

React

React js Top Front-End JavaScript Frameworks

Started by Facebook in 2011, React has rapidly gained popularity as a comprehensive library for developing dynamic user interfaces.

React too has a component-based structure, which makes front-end development easier and faster. Because of its DOM programming and efficient server-side rendering, React helps even complex apps run very smoothly. It also has a positive impact on the SEO of web apps. React has an optional syntax extension that enables developers to write their own components.

It doesn’t take long to learn React because it’s based on plain JavaScript and has a well-defined life cycle.

The Good

  • Reusable components make React a powerful tool to collaborate with other parts, too.
  • The virtual DOM enables developers to create seamless and consistent apps.
  • React Hook is an excellent component that enables developers to write components without classes, making it easier to learn.

The Not-so-good.

  • JSX is a complex tool to learn in the beginning, which may create some difficulties.
  • React is more suitable only for developing the front-end of apps.

When to Use React:

React is an incredible tool for developers to use when developing a user interface. It's great for single-page apps and interactive interfaces. React is the most robust framework for building a user interface quickly. It allows you to reuse components, saving developers time.

When Not to Use React:

As mentioned in the shortcomings above, we don’t recommend using React for beginners. That’s because JSX might be a bit difficult to learn for developers who don’t have enough experience. Also, if you don’t have good knowledge about JavaScript, React won’t be a good option.

Vue.js

Vue js Top Front-End JavaScript Frameworks

While Angular is supported by a giant like Google and React by Facebook, Vue.js doesn’t have any backing from a strong tech company. It was created and is maintained entirely by the community.

Vue.js has become quite popular because of its flexibility and scalability. The main reasons developers love this framework are its ease of setup and its integration with different languages. The most distinguishing feature of Vue.js is that it's incredibly lightweight. Its file size is as small as 20 kilobytes, so you can set up and start using it within seconds.

The Good

  • You can use it as a library for building UI elements in a project, and also as a full-fledged framework for building an entire project.
  • Vue is component-based and also works on visual DOM.
  • It has two-way data binding which means the changes can reflect as soon as they appear on model and view, vice versa.

The Not-so-good

  • Even though it's components-based, the components aren’t as stable as its counterparts.
  • Language can be a problem in some plugins, as they are in Chinese.

When to Use Vue:

Setting up an environment is extremely easy with Vue. You don’t need a tool like Webpack to get started with your project. Hence, its flexibility and scalability make it a preferred option for larger projects.

When Not to Use Vue:

Vue still has a lot to earn in terms of community support. If you think you can get community support for solving the complexities, Vue might not be a good choice. Additionally, the instability of components is also a concern. So the apps requiring stable components won’t do well with Vue.

Ember.js

Ember js Top Front-End JavaScript Frameworks

Ember is an open-source JavaScript UI framework built with an MVVM (Model View-View Model) pattern. It offers full-stack development options with efficient debugging solutions.

You can use elements from its vast collection of powerful add-ons, and you can add your own elements to it as well. One of the major principles of the Ember framework is stability without stagnation. Ember supports two-way data binding efficiently, so it’s a reliable framework for complex user interfaces.

The Good

  • Extensive ready-made features, which mean you get the best practices built in the framework.
  • Front-end developers can create large applications by writing fewer codes.
  • Smooth and secure code transfer with deprecation warnings when a new version is about to be released.

The Not-so-good

  • Ember might suffer from a slower syntax and hence updates.
  • Larger applications are better with Ember, but smaller ones may find it a heavy framework.

When to Use Ember:

Are you planning to build an app with a rich interface? If yes, then Ember is the way to go. It provides all the facilities of a technical front-end and is readily configurable. Plus, it has an impressive routing system, making it perfect for large apps with rich features. It also fulfills the need for page rendering as required, with its useful binding and custom properties.

When Not to Use Ember:

If your development team is still in its initial phase, Ember won’t be a good choice as it can get a bit costlier. Ember comes with some complexities that require appropriate experience and business logic. As said above, it's better for larger apps, so smaller apps with simple Ajax won’t be able to harness Ember’s true potential.

Svelte

Svelte Top Front-End JavaScript Frameworks

Like many other reactive JavaScript frameworks, Svelte too is a component-based framework, but with vital differences.

Firstly, Svelte is a compiler and works as a framework without a framework. It doesn’t run on the browser. Instead, you can run it as a compiled vanilla JS code. It eliminates the need for virtual DOM and results in exceptionally faster performers.

No matter how great the size of the code is, your app literally works as if it has a pre-loaded code. Developers working on the Svelte framework enjoy flexibility in writing code like no other framework.

The Good

  • It uses just the basic three languages, HTML, CSS, and JS, to build components.
  • It has significantly less boilerplate compared to other frameworks.
  • Its in-built mechanism identifies unused CSS selectors, helping developers get rid of all the unnecessary code.

The Not-so-good

  • Since it's the latest framework, it doesn’t garner much support from the front-end community.
  • Even though it has JavaScript libraries, it still lacks some proper tooling for easier development.

When to Use Svelte:

Small projects and smaller teams work with Ember perfectly. Since It's pretty new in the market, the community base is still growing. Hence, it's better not to use Ember for bigger projects.

When Not to Use Svelte:

As mentioned above, bigger projects might not go down well with Ember as of now. The reason behind this is it doesn’t have proper tools yet for larger apps. Also, the complexities, bugs, and questions in the later stages of development would be harder to solve with the lack of community support.
