In computer programming, a framework is a foundation over which programmers can build their software. In a similar way, a JavaScript framework provides a base for the convenience of the programmers.

It helps by providing a set of pre-written codes so the programmers would not need to start from scratch. Thus, they can use the framework as a structure for the JavaScript program or application they are working on.

What Does a JavaScript Framework Do?

A JavaScript Framework is a very important part of modern web development. There is no one framework for the codes, as every JavaScript framework serves a different purpose. The frameworks are easy to apply as every application or website has some common features. It thus makes the task less laborious and time taking.

Just the way our skeleton provides a framework for the support and shape of our body, a JavaScript framework serves as a basic foundation for a given website or application.

What's the Difference Between a JavaScript Framework and a JavaScript Library?

A JavaScript library consists of various functions that can be called upon by the application or website to perform specific functions. It thus provides predefined functions to boost the process of website or application development.

JavaScript framework, on the other hand, is more generic in nature. The developers cannot call upon the framework for the sake of a task. It provides the foundation and thus defines the design of a website or an application. 

Top 10 JavaScript Frameworks

1. Angular

It is a framework written in TypeScript and developed by Google. It is an open-source web application framework used for developing single-page applications (SPA). 

Features:

  • It gives you free control over adaptability and helps to meet huge data requirements. 
  • With easier DOM manipulation and two-way binding, the incredible tooling provides simple, declarative, and effective templates. 
  • Developers can also get instant help and feedback related the Angular with almost every IDE.

Vue.js is a free, open-source JavaScript framework that is a progressive front-end framework. It is approachable, easy to learn, and can be used for both small and large applications. 

Features:

  • Its components contain reusable codes and pre-defined options for custom elements. 
  • The framework uses an MVVM structural pattern that separates the GUI from the model's business logic.
  • Even though it is a relatively young framework, it has already gained popularity due to its numerous features. 
  • Vue.js can also be used for creating a high-end SPA with the dual integration mode.

4. Ember.js

Released in 2011, ember.js is a free JavaScript framework. From SPAs to enterprise applications, the main objective is to build interactive UIs regardless of the website size. 

Features:

  • It has a component-based approach and is easy to learn with components central to the framework. 
  • The features of Ember.js support a two-way data binding. This makes it more suitable for working with complicated UIs and larger projects. 
  • The focus on configuration ultimately reduces the number of possible errors but only at the cost of customization.

Features:

  • Mithril has quite a small and simple API.
  • Interaction with other libraries is easy.
  • It is lightweight and has a good templating engine.
  • It has a virtual DOM and provides compilable templates for designing a website or application.
  • It provides routing and XHR utilities, thus resulting in an out-of-the-box performance.
  • It is declarative and thus reduces code complexity.

7. Node.js

It is an open-source runtime environment built to execute JavaScript outside a web browser. 

Features:

  • Node.js is easy to learn and scalable.
  • It works on cross platforms.
  • There is hardly any buffering due to reduced processing time.
  • It consists of an event-driven I/O, and thus it doesn't wait for the API to come back with data.

8. Polymer

It is a JavaScript library developed by Google. It is an open-source framework and is well suited for Single Page Applications. The polymer has a vast area of application as it supports both one-way and two-way data binding. Its features help developers to create custom elements.

Features:

  • Customized and reusable elements can be used 
  • Widgets can also be reused, and the elements of a website or application can be created without many hassles.
  • Google material design paves the way for faster and easier development of mobile applications.
  • It is flexible because, with the help of HTML imports, users can access custom elements.

9. Aurelia

This JavaScript framework is useful for developing extensive websites, but it can be difficult to learn. Nowadays, this framework is not as popular as it once used to be.

Features:

  • Aurelia's components consist of HTML views as well as JavaScript view-model pairs.
  • Web standards are given full attention and are completely adhered to.
  • Its features make it easier to work with other tools.
  • The modern structure of the framework also provides commercial and enterprise support.

10. Backbone.js

Backbone JavaScript framework is used in the case of Single Page Applications. It is popular due to its features which allow complex functions with comparatively lesser codes. However, debugging could be an issue at times.

Features:

  • Its easy-to-use library assists in separating the logic between the business and the user interface.
  • This framework has a hard dependency on Underscore.js. On the other hand, it has a soft dependency on jQuery.
  • Backbone.js framework has a free and open-source library where over 100 extensions are available.
  • It aids in a well-organized format of application or website with a good structure.

Which Is the Best JavaScript Framework?

Even today, JavaScript continues to be the leading language when it comes to web development. But all the various frameworks have their own unique features, pros, and cons, which must be kept in mind while making a choice.

The specific requirements of the website or application must be clear before deciding upon the framework. This is because every framework has some exclusive features, and it is important to understand which one suits our requirements best. Besides this, one must also consider the complexity, learning curve, and compatibility documentation of the framework.

Choose the Right Framework for Your Website

JavaScript frameworks are essential to optimize the whole web development process and save quite some time, effort, and even money. However, there is no single framework that is perfectly suited for all projects. Each one has its own advantages and disadvantages and is to be chosen according to the project requirements. Thus, to zero on one specific framework, you need to consider several factors like:

1. Existing Toolstack 

It is crucial to make sure that JavaScript is used as the front-end programming language for the given website or application. For example, if Java or Python is used, one must choose from their respective frameworks.

However, you need to consider more factors in case you are looking to apply a framework to a pre-existing site. For example, one needs to check the money and time required to build a new website with a framework versus implementing the same framework in an already existing code.

2. Complexity

It is very important for you to know the scope of the project. This is because some frameworks can support large applications, while some can just be used to build SPAs. Thus, you must know which framework will support your project necessities better.

3. Performance Requirements

The speed of your website is another important factor that you need to consider. Due to their focus on virtual DOM, some frameworks would prioritize quick responses. On the other hand, if your project demands more built-in functions and control, a more robust framework would be a better option. 

4. Technical Competence

Some JavaScript frameworks are easy to learn and simple to implement, while others might be a bit complicated but may offer far more features. If you want to use a framework soon, you may opt for an easy-to-use framework depending upon your proficiency. But a complex framework can offer more benefits in the long run if programming is your expertise or if you have the time to learn.
