Choosing the Best JavaScript Framework In 2024

JavaScript (JS) is undoubtedly the most used scripting language that powers almost all modern websites and web apps, along with HTML and CSS. It enables developers to add interactive elements to their UI that end-users can interact with. As the need for better and more efficient UIs (user interfaces) and faster development is increasing, more and more developers are leveraging front-end javascript frameworks. A JavaScript framework is designed to simplify and accelerate the front-end development process.

However, with numerous new and old JavaScript frameworks available in the market, many developers often find it challenging to choose the right one for their project. This article aims to make this process easier for you. 

In this article, we’ll discuss various factors you need to consider before choosing a JS framework. We’ll also explore features of some of the best and most popular JavaScript frameworks, such as Ext JS, Angular, and React.

What Does a JavaScript Framework Do?

A JavaScript framework provides a collection of pre-written JavaScript code libraries and functions for routine tasks involved in web development. This way, developers don’t have to write code for common and repetitive tasks again and again. 

There are different types of JavaScript frameworks for different purposes, offering different features and functionalities. These frameworks are widely used in modern web development. 

These frameworks offer various benefits, such as:

• Faster and simpler development process
• Cost and time savings
• Enhanced developer productivity
• Improved efficiency
• Better developer experience

JavaScript Frameworks: Key Features

Component-Based Architecture

Modern JavaScript frameworks support component-based architecture. It involves breaking down the UI into reusable and self-contained components. 

This means each component has its own style, structure, and behavior. This makes it easier to maintain the app as the changes in one part of the codebase don’t affect any other part of the app.

Moreover, developers can reuse components across different parts of an app or across projects. This saves time and enhances productivity.

Data Binding

A good JavaScript framework provides powerful mechanisms for data binding. This helps with the automatic synchronization of data between different parts of the application. 

Different JavaScript frameworks offer different data binding capabilities. For example, some frameworks support one-way data binding, some support two-way data binding, and some support both.

• Two-Way Data Binding: Changes in the UI are reflected in the model and vice versa. Ext JS and Angular offer two-way data binding.
• One-Way Data Binding: Changes in the model or state automatically update the corresponding UI elements. However, changes made in the UI do not automatically update the model. React uses one-way data binding.

Routing

Most frameworks include built-in routing capabilities/ solutions. This enables developers to define their app’s navigation structure. Moreover, with routing, developers can map URLs to specific components or views. This allows for the creation of single-page applications (SPAs) with multiple views.

State Management

State management is essentially the process of managing and synchronizing the state (data) of an app across various components. In complex web apps, managing state effectively is essential to maintain app consistency and performance.

Good JavaScript frameworks provide ways to manage state across components. This makes it easier to handle complex state logic, especially in large-scale web apps.

State management tools provided by JavaScript frameworks often include:

• Centralized stores and state management pattern 
• State management libraries
• Reactive programming paradigms

Difference Between a JavaScript Framework and a JavaScript Library

JavaScript frameworks and libraries are often considered the same thing. However, there is a slight difference between these two.

A JavaScript framework is a comprehensive toolset that provides the foundation for building a web app. It guides developers through the entire application development process. It provides a structured architecture and built-in functionalities like routing and state management.

On the other hand, a JavaScript library provides several pre-defined functions that developers can call in their apps to perform specific tasks. These can include DOM manipulation, data handling, or utility functions. 

Factors to Consider When Choosing the Best JavaScript Framework

Project Requirements

Consider your project requirements, such as the web application’s size, complexity, scalability and performance requirements. This will help you select the best JavaScript framework for your specific project.

For example, if you’re developing an enterprise-grade web or mobile application involving complex tasks and scalability requirements, you should choose a Javascript framework like Ext JS that is designed specifically for building enterprise-level web or mobile apps. 

However, if you’re creating single-page web applications, Angular is a good option with data binding and cross-platform compatibility.

Learning Curve and Developer Community

In the highly competitive modern software development world, it’s crucial to create high-performance web applications faster.

For this reason, you need to choose an easy-to-use and easy-to-integrate framework. Otherwise, you’ll spend more time learning the framework instead of creating web apps faster. 

A popular JavaScript library has extensive documentation and additional learning resources. These resources provide details regarding the features, capabilities, and implementation of the framework. This make the integration quick and easy.

Moreover, it’s best to assess if the framework you’re choosing has a big developer community. This way, you can ask for help regarding anything related to the framework from other experienced developers.

Performance and Optimization

The best JavaScript framework is designed to work efficiently in different kinds of web apps and handle data seamlessly. 

For example, Ext JS offers a high-performance JS grid that can process millions of records efficiently without affecting the app’s performance, improving user experience.

Integration With Other Libraries

A good Javascript framework comes with most of the necessary tools developers need to create feature-rich, responsive, and interactive user interfaces. 

However, you might need additional libraries for data processing, rich text editing, DOM manipulation, and more. Thus, you should assess if the framework supports integration with other libraries. 

Moreover, you should also check if the framework has its own ecosystem of extensions that allow you to access additional valuable features beyond the framework’s scope.

Long-term Viability

Assessing the framework’s long-term viability is another crucial factor to consider to ensure your app keeps functioning efficiently. 

For instance, you can check if:

• New and improved versions are released frequently
• New features are added to the framework
• Whether the framework has an active community.
