When the 2020 version of the Stack Overflow poll appeared online, developers, programming enthusiasts, and publicists were not surprised to see the language taking the top spot as the most used language. JavaScript had held the top spot for seven years in a row, and it didn’t look like that would change in 2020: 67.7% of developers said they use it frequently.

 

So it’s only logical that so many people debate which of the many JavaScript frameworks available is best for doing their job. It’s clear that JavaScript developers tend to favor one or the other based on their personal experience, so it’s hard to argue that one is better than the other (without the project’s context, mind you). But there are any clear preferences in the JavaScript landscape, a handful of frameworks that have become somewhat indispensable to developers (at least that’s what happened to the engineers at BairesDev).

 

So we’ll review 4 of the most influential and popular JavaScript frameworks. These can expect to become even more critical in 2021 and beyond as more and more people use them. So we’ll look at their pros and cons so you can decide which one is best for your project. But first, let’s examine why JavaScript is so popular and why its developers are in high demand. 

 

 

 

What do JavaScript programmers do?

A JavaScript developer is accountable for designing and building applications and software using JavaScript. As JavaScript is one of the most widely used programming languages, it provides developers with a rich feature set that is particularly suited to front-end development. JavaScript developers thus create web pages with user experience and interaction in mind. 

 

Developers can use it to code back-end applications and even use it for an entire project (thus becoming full-fledged JavaScript developers). Developers can access the extended capabilities of JavaScript through frameworks and libraries to focus on the former here. 

 

 

 

| React

React is probably the best-known JavaScript framework (as evidenced by its popularity in the Stack Overflow survey). Since its release in 2013, it has steadily gained a broader user base, mainly because it can use it for native development. It is maintained and supported by Facebook probably isn’t insignificant either, as this ensures that React regularly receives new features and updates. 

 

Overall, React is an excellent option for developers and companies who want to create user interfaces, single-page, and mobile apps, thanks to its fast download speed. 

 

 

 

Benefits:

 

Virtual DOMs: React uses a local and reduced version of the Document Object Model that further abstracts from these abstractions to perform computations faster and without being tied to browser specifics. 

Reusable Components: React allows for arbitrary reuse of code components at different levels to save time when working with it. React components are isolated, meaning you can change one element without seeing the changes affect the others. 

Downward data-binding: React allows you to work directly with components. With low data binding, you will see that parent structures are not affected by the changes you make to their children, making the overall code more stable. 

Open source: Facebook made React open-source upon release, which was a great thing that spawned a vast community of developers working to create new tools and apps.

 

 

Cons:

 

JSX: React does this syntax addition that allows you to use HTML in JavaScript code which can be a good thing (especially for security reasons). Still, it can also make it harder for you to learn how to use the framework because of the enhanced complexity.

 

Too numerous updates: updates in the software world are frequently a good thing – until they stop being one. In React, they suggest new features and capabilities, but they also usually change React, which will cause you to have to relearn things you’ve already mastered more often than you’d like. 

Inadequate documentation: React evolves that developers struggle to write the fitting instructions for each functionality, so most React documentation is scattered or too specific. 

 

What do JavaScript developers do?

 

A JavaScript developer is accountable for planning and building applications and software using JavaScript. JavaScript, one of the most widely used programming languages, offers its developers a multitude of features primarily suited to front-end development. Thus, JavaScript developers create websites with user experience and interaction in mind. 

However, JavaScript is not only limited to the front-end. Developers can use it to code back-end applications and even use it for the entire project (becoming full-fledged JavaScript developers). Developers can access advanced JavaScript functionality through frameworks and libraries, focusing on the former here. 

 

| React

React is arguably the most well-known JavaScript framework (as evidenced by its popularity in the Stack Overflow survey). Since its release in 2013, it has steadily gained a larger and larger user base, mainly because it can use for native development. It is maintained and supported by Facebook-specific doesn’t hurt either, as it keeps new features and updates to React fresh. 

Overall, React’s fast download speed makes it a good option for developers and businesses to create user interfaces, single-page applications, and mobile apps. 

 

For :

 

Virtual DOM: React uses a local, simplified version of the Document Object Model and further abstracts from these abstractions to perform computations faster and without being tied to browser specifics. 

 

Reusable components: React allows you to reuse code components from different layers at will, saving you time in development. React parts are isolated, which means you can change one without affecting the others. 

Downstream data-binding: With React, you can work directly with components. Thanks to downstream data binding, you’ll find that parent structures are not affected by changes to their children, making the overall code more stable. 

 

Open Source: Facebook made React open source at the time of its release, which has been a fantastic thing that has led to a large community of developers working to create new tools and applications for it.

 

Disadvantages:

 

JSX: React uses this syntax extension that allows you to use HTML in JavaScript code which can be a good thing (especially for security reasons), but it can also make it challenging to learn how to use it of its increased complexity.

 

Too many updates: updates are often a good thing in the software world – until they are not. In React, they mean new features and capabilities, but they also usually change React. As a result, you’ll have to relearn things you already know more often than you’d like. 

 

Inadequate documentation: React is evolving at such a fast pace that it is difficult for developers to write guides for all the features. As a result, most documentation on React scatters or is too detailed. 

 

| Angular

Angular is a more mature choice of JavaScript framework. Released by Google in 2010, Angular extends HTML into applications, interprets attributes, and performs data binding, making it a top front-end developer’s Choice. As part of the popular MEAN stack, it includes features such as MVC architecture, TypeScript support, and dependency injection.

 

Angular is also great if you are working on a large application project, looking for scalable architecture, or even if you are developing a single-page application.

 

 

 

Pros.

Two-way data binding: In an MVC architecture, the view also changes when the data in the model changes. This bidirectional binding saves programming time by eliminating the need to synchronize view and model data constantly.

Dependency Injection: Angular allows you to detach components from dependencies by using injectors to define dependencies as external elements, making it easier to manage and test these components and enable them to be reused.

Strong community: Angular is also one of the most popular JavaScript frameworks. As such, there is an active community of resources, discussions, and third-party tools to help you learn and grow with Angular.

 

 

Cons

Poor performance: although you can use it for large applications, you need to be careful when developing with Angular. Complex Angular applications tend to run slower and perform worse (especially those built using other frameworks).

 

Difficult to learn: While you might say that versatility is a great thing (and it certainly is! ).

You’ll find that there is such a thing as too much versatility in Angular: there are so many different ways to do the same thing in Angular that it’s confusing and makes learning difficult.

 

 

| Vue

Vue is one of those frameworks that is talking about more and more as time goes on. Its popularity is sure to grow in 2021. Don’t let its small size fool you, and it is a very flexible and powerful progressive framework with high reuse value and fast performance that has captivated people since its release in 2014.

 

Vue uses it for building web interfaces and single-page applications, but it can also use it to create desktop and mobile applications when combined with the Electron framework.

 

 

Pros:

 

When we say that Vue is light as a feather, it is as tiny as a frame can be, making it easy to download and install and complete your application easier to find and use. 

Two-way responsive engagement: Vue inherited this feature from Angular, but Vue makes it responsive, which means that updating data is more straightforward and more accessible, which is particularly useful in applications that require real-time updates, as changes replicate as needed without affecting overall functionality. 

Reusability and readability of components: Vue uses encapsulated components that can be easily reused in multiple applications and are more readable and understandable. Encapsulation also facilitates unit testing, as it is easier to test individual components. 

Robust out-of-the-box tools: Vue comes with a suite of powerful tools that give you more power over your projects, including end-to-end testing tools, an add-on installation system, and even its debugger.

 

 

Cons :

 

Complex response: bi-directional data binding is excellent, but it comes at a price: you have to monitor the response system, which often makes errors when reading the data. So you have to follow Vue’s documentation to the letter to avoid them in the process, which is not without complexity. 

Limited resources: While Vue is mighty right out of the box and has tons of great tools to showcase, it’s not as significant as other frameworks (notably React or Angular). The plugins are more limited, which can mean that your work on Vue can be limited here and there. 

 

 

| Ember

 

Ember isn’t as popular as other frameworks, but that doesn’t mean developers don’t like it. People who have chosen Ember since 2015 swear by it, not least because of the structured coding style it offers. In other words, it’s tough to make mistakes using Ember because there is usually only one way to do a sure thing.

 

Based on the MVVM model, you can use Ember to create complex web applications very quickly. You can even use it to build desktop and mobile applications, although its strength lies in developing web applications. 

 

 

 

For :

Contract advantage over configuration: Ember uses naming conventions, which then generate code automatically. Using this principle saves a lot of time, as you don’t have to write large amounts of repetitive code, freeing you from unnecessary tasks. 

Ember CLI: Widely regarded as the best CLI of all these frameworks (a claim that is of course disputed by many), Ember’s CLI makes it easy to create and adapt code to the proper structure, taking into account the correct dependencies. 

Ember Inspector: is a quirky debugger that is nothing more than a browser extension that allows you to monitor and modify your Ember applications in real-time, making it easier and faster to find bugs and problems. 

 

Cons

Large size: Ember is the opposite of Vue, as it is one of the most prominent JavaScript frameworks available, which means that it is best suited for large projects, as using it on a smaller scale could lead to many problems drawbacks. 

Unnecessary abstractions: some claim that Ember is more like Ruby on Rails than JavaScript

 

In some respects, this is true, which is not necessarily bad, except for the unnecessary abstractions that can over-complicate projects.

Hard to learn: One of the most significant drawbacks is that, despite its power, Ember can be hard to understand, which is especially true for beginners or people interested in simple projects, as Ember offers much more at the expense of simplicity. 

 

JavaScript framework trends that will be strong in 2021

 

If you’ve been paying attention to the evolution of JavaScript frameworks lately, you’ll notice that this list doesn’t add much new. These frameworks have established themselves as the best JavaScript frameworks and still have room to grow. So you can expect their popularity to continue to grow means we won’t see many changes, but that’s not necessarily a bad thing. React, Angular, Vue, and Ember have stood the test of time, and their growing popularity is good news for anyone looking to get the most out of JavaScript.
