React vs Angular: differences, advantages and disadvantages in 2025

React or Angular... This is undoubtedly one of the most frequently asked questions when diving deeper into the JavaScript programming language. But is it really relevant? 👀

To help you make the best choice for your projects, we’ve compared these two technologies in detail. Here’s everything you need to know about their advantages and disadvantages, and why this duel might not be a duel after all.

React

React, also known as React.js or ReactJS, is a library that enables the creation of graphical interfaces for websites.

Advantages ✅

As in other comparisons we’ve made (such as React vs React Native), React boasts many advantages.

👉 It is simple and flexible

Being a library and not a framework, React offers greater freedom in how you structure your project.

👉 It has a (huge) community

React is simply the most widely used JavaScript library among developers worldwide, according to Stack Overflow.

👉 It enables highly modular code

React allows you to create reusable components, which are self-contained blocks of code that can be used in multiple parts of your application. This modularity simplifies the management of large applications, as each component can be developed, tested, and maintained independently.

By using reusable components, you improve code consistency and facilitate long-term maintainability.

👉 It updates only what is necessary

One of React’s great strengths is its Virtual DOM. This term, coined by the React team, refers to a virtual DOM that is separate from the DOM displayed on the page. This allows React to update only the parts that need to be modified without unnecessarily refreshing the entire page for a simple dynamic text change.

This feature ensures optimal performance, particularly for interface updates.

Disadvantages ❌

Because nothing is perfect, here are some disadvantages of React.

👉 It takes time to truly master React

Learning React is not complicated, but mastering this JavaScript library is another story.

Concepts like JSX or managing states can be a bit confusing for beginners. Think back to when you first learned about object-oriented programming: that’s exactly how it feels. 😁

Angular

Angular, also known as AngularJS, was first introduced by Google in 2010. It wasn’t until 2016, six years later, that Angular 2 (commonly referred to as Angular today) was released.

Advantages ✅

Angular also has many advantages.

👉 It offers a complete framework

Unlike React, Angular is a framework. But as you’ve read earlier in this comparison, you now know the difference! 🙃

It provides an integrated set of tools to simplify the development of your web projects.

👉 It uses TypeScript

We’ve already done a comparison between JavaScript and TypeScript in a previous article. If you don’t know what TypeScript is, think of it as an improved version of JavaScript with static typing: it’s impossible to create a variable in TypeScript without specifying its data type.

This is both an advantage and a disadvantage:

• The advantage is that using TypeScript results in more robust and maintainable code;
• The disadvantage is that you need to learn it (of course!).

👉 It offers powerful tools

With built-in features like RxJS for data stream management and Angular CLI for easy project management, Angular is ready for complex applications.

Disadvantages ❌

Because nothing is perfect, Angular also has some disadvantages.

👉 It is complex to master

If you thought React was hard to master, you haven’t seen Angular yet. 😅 It has a steeper learning curve than React, especially for less experienced developers.

With its structure (being a framework) and advanced concepts (like modules and services), the task becomes more challenging for those who want to give it a try.

👉 Performance is generally lower

Angular applications can be heavier in terms of size and less performant than those built with React, especially for small applications.

👉 Frequent updates that change everything

Angular has undergone several major versions, which can complicate migration and compatibility in long-term projects—unless you enjoy spending nights updating projects. 🤔

Comparison Table

Here’s a summary:

Should You Choose React or Angular?

The choice between React and Angular really depends on the nature of your project and your specific needs.

If you need high flexibility and prefer to select tools tailored to your project, React might be the best choice. It’s also a great starting point for simple front-end applications or projects with smaller teams (or if you’re working alone).

If you’re looking for a complete solution with a well-structured architecture from the outset, especially for a complex large-scale project, Angular might be more suitable. Its ecosystem enforces conventions that promote maintainable code.

There is no one-size-fits-all answer. Both technologies have their place depending on the context of your project and the skills of your team. But generally, React is recommended for developers starting with JavaScript.

For statistics lovers, here’s a study published by State of JS showing React as the clear winner against Angular in market share.

Related Questions

Here are some common questions we receive when assisting our students:

Yes, but not always. Generally, thanks to its Virtual DOM, projects built with React are executed and updated faster. This is especially true for small to medium-sized projects.

Yes, based on the statistics shared at the beginning of this comparison. However, your choice of technology should depend on your needs rather than its global popularity.

You can also observe this trend on Google Trends.

No significant difference is noticeable between the salaries of a React developer and an Angular developer. However, there are generally more job opportunities for React.
