Therefore, you need to carefully decide the frontend framework before starting your project.

To simplify your task, we have carried out thorough research and listed the best frontend frameworks based on these factors like popularity, features, ease of integrating libraries (with other Libraries), availability of learning resources, etc.

Moreover, we have also listed the pros and cons of frontend frameworks, when to pick a framework, and when to avoid using it. It helps you to distinguish the most popular frontend frameworks and select the suitable ones for your project.

Let’s get a little bit technical now.

11 Best Frontend Frameworks to Use in 2021

Here, we have summarized the most popular frontend frameworks which you can consider for your next project.

1. React – A Javascript Library For Building User Interfaces

React

React is one of the most popular frontend frameworks since its inception. React is an open-source and component-based JavaScript library with JSX syntax.

Jordan Walke, one of the Facebook software engineers, created a React prototype while facing issues in working on a Facebook network update.

He used XHP and JavaScript combination to build a library in 2011. Facebook later released the open-source JavaScript tool with the name ReactJS in 2013.

The main feature of ReactJS is virtual DOM, which improves the complete user experience.

It provides excellent performance; it is SEO-friendly and allows you to write JavaScript code with ease.

Pros of React Cons of React

► React works well with isolated components; hence you can utilize the components anytime you want.

► Virtual DOM ensures quick rendering.

► One-direction data flow provides stable code.

► It has a vast community of developers across the globe.

► Requires more libraries to develop complex apps and websites.

► Developers find it challenging to understand JSX.

► It works only on the user interface layer.

► Poor documentation.

When to use React?
If you want to develop user-interfaces for single-page web apps and mobile apps then you can go with ReactJS.

However, if you want to build highly complex applications, you can utilize popular libraries, such as Redux and React Router.

Lastly, if you want to develop static and dynamic websites and web applications, you can also utilize Next.js, a popular open-source React frontend framework.

When not to use React?
If you don’t have good experience in JavaScript development, then you shouldn’t go with React. Moreover, learning JSX is a bit challenging for naive developers.

2. Angular – The Modern Web Developer’s Platform

Angular

Angular is one of the best web frontend frameworks whose source language is TypeScript. It is mainly a modified version of AngularJS and developed by Google.

It is a component-based framework and offers 2 way data-binding. Due to this feature, there is an instant synchronization between model and view components, which means any change in the model gets reflected in view and inversely.

Angular utilizes a hierarchical dependency injection system with the help of declarations, constructor functions, and providers.

It also utilizes flux architecture, where change detection is possible via unidirectional data flow, thus enhancing the speed of developing apps.

Pros of Angular Cons of Angular

► Due to its lazy loading feature, applications run faster.

► Independent components are quicker to replace, handle, and scale-up.

► Due to independent and self-sufficient components, it is reusable and test-friendly.

► Angular requires TypeScript, which ensures expressive code, improved navigation, and better-quality product.

► It possesses a massive community of developers globally.

► Suitable for rapid prototyping.

► The main disadvantage of Angular is that it has very few SEO options and limited accessibility to the search engine crawlers.

► Due to its complex structure and size, various dynamic apps do not perform as per the expectations.

► It has a steep learning curve; hence developers find it challenging to learn many concepts.

When to use Angular?
If you are planning to build progressive web apps, enterprise-based apps, and dynamic web apps, then go with Angular.

Here, we recommend you develop a progressive web app because it offers various benefits. Moreover, some of the leading organizations worldwide have built progressive web apps to improve their business and provide an enhanced user experience. To know more, check out these PWA examples.

When not to use Angular?
