The most important features and advantages of ReactJs over AngularJs

The most important features and advantages of ReactJs over AngularJs we are going to review in this article. In the past, AngularJs was treated as the best choice for making a framework for a web page, most projects were done through it due to its popularity and capabilities it provides over others.

Perhaps there are objective reasons for this consideration, which made many developers rely on AngularJs frameworks and nothing else.

Now the React.js library has come to the fore, replaced others, most developers use it, they considers it the ideal library to do a unique framework work, because of its distinct tools.

why React.js is better than AngularJs?

One of the most important features and advantages of ReactJs is that I found many reasons why React.js outperformed AngularJs, as there were many instability and compatibility issues when using AngularJs, which no longer exists with the advent of React.js.

After the release of AngularJs 2 in 2016, most developers raised their expectations for AngularJs for a new release that continues to shine.

On the other hand, during the first months of AngularJs2's release, things got tough, it seemed like a huge shock to a large number of developers.

Despite many years in which Angular team worked hard on developing the second version and its continuous attempt to bring it to light in a distinctive way, the result of their efforts was disappointing, it was not as expected, especially in terms of stability, performance and developer experience.

A large amount of errors appeared in the second version, as the developers faced many problems, the problem of instability for this version led many of them to leave this framework and search for another one to be calmer and more stable.

Disadvantages of Angular projects and its incompatibility with freelance developers

One of the important observations that seemed to many developers is that Angular projects are mostly giant projects that are not suitable for individual work for Freelancers, as they require teamwork.

As a result, most freelance sites and platform projects use ReactJs much more than projects which are done with Angular.

Most companies with complex projects have their developers to work full-time jobs at their offices.

React.js library version specifications

As for React, it was characterized by a kind of smoothness and the version has the ability to move from version 15, which was released in mid-2016, to the current version without any problems or complications.

Despite the complexities and many additions that the React.js library has seen like Hooks and others, it is still very well compatible with various older versions.

It can be argued that the reason why developers abandoned AngularJs and switched to the React.js framework is because of AngularJs itself and not because React.js is superior to others.

The importance of React.js in helping to learn JavaScript

It is well known among the developer community that when you become a React developer of the highest level, you will necessarily be a JavaScript developer of the highest level as well!

This statement is true to a large extent, when you use the React library, you are writing 100% JavaScript codes.

The codes we write in HTML are also written in JSX format, which is in the end JavaScript codes.

Moreover, each React component is originally a function that accepts handling of properties (Props), since the advent of React Hooks, we can set the state of the component inside these functions, which in the past were the preserve of Class components.

One-way data flow feature

One of the most important features and advantages of ReactJs, and one of the most important things that distinguishes the React library from other JavaScript libraries and frameworks is a feature called the one-way data flow feature.

The higher the degree of difficulty and complexities in the application, the value of this feature emerges.

From the context Unidirectional Data Flow, everything must start from the setState() function, a developer must use it if he wants to change a certain state in the application.

Whenever the state is updated by setState() the Virtual DOM rebuild occurs through the new state and update of the UI.

This way you can only control any state, even the Inputs, after going through the state update. setState()




  onChange={(event) => this.setState({ name: })}



This command is not present in Angular nor in Vue as the Status or Model changes in both directions.


<input [(ngModel)]="name" type="text" />
