Which one is better between Angular and ReactJS?
First of all, both are the frameworks of JavaScript which can be used for client-side web development to make rich interactive web pages. There have been lots of version releases over a period of time. Currently, Angular is having its stable version 8 whereas React is having the 16.10 as of Oct’ 19.
We will see the major differences below:
1. Framework Vs Library
Angular is a complete framework that comes with the number of supporting libraries to fetch the data from the server-side, to implement routing, two-way data binding and so on.
ReactJS is just a library that can be used to create the rich user interface and it does not come with the built-in libraries but there are multiple open source-compatible libraries available to implement everything.
2. Virtual DOM Vs Actual DOM
React uses the concept of virtual DOM which means the copy of the actual DOM is created in the memory. Every change in the states creates another VDOM and the comparison between these two takes place. Only the changed part gets reflected in the actual DOM. Thus, it becomes faster.
But, in the case of Angular, it re-renders the complete page for every change detection. However, the latest ‘Angular-Ivy’ renderer does it in zones and makes it even faster than the previous one.
3. One-way Vs Two Way Data binding
In React, the flow of data takes place only in one direction. The state is passed to the view and to its child component makes it predictable.
In Angular, the data flow takes place in two way i.e. from the view to the controller and vice versa.
4. Templates Vs JSX
React uses the JSX which returns the UI elements and its faster for execution when having multiple child elements.
In Angular, it uses templates which are normal HTML code for DOM creation.
5. Typescript Vs JavaScript
React is based on Javascript and uses ES6 features. However, It can also be written into typescript.
Angular V2 onwards are based on typescript and it gets transpiled into javascript. However, it can also be written in CoffeeScript and javascript inside typescript files.
So, more or less both are the best platforms for web development. There are some differences which are as similar as between ‘Tea’ and ‘Coffee’. There are lots of lovers of both so depending upon your choice, you have to decide the cup.
