Before Angular and React:

Javascript is a  single threaded,were programs works by step by step only,Before Node Js,Javascript is used only on client sides,were it take care of DOM,And also it’s difficult to write the code in Javascript.Then comes  Angular and React  both are developed by Javascript and they are asynchronous.

Angular Js Vs Angular :

Angular one of the biggest evolution In the market. Google released Angular js 1.x and made an open source in 2010 mainly for web application, and also business applications are made by using Angular js because it is open source and cross platform.It’s an Framework of Javascript.In 2014 Angular 2 was released,It was 5 times faster than Angular js, It’s an components based mobile as well as desktop applications they using typescript(superset of javascript).typescript supports ES6 and typescript was developed by Microsoft.

Angular Vs React:

Angular latest version is 8.x,April 2019 released 8.x unstable version by google.React latest version 16.8.0

1. Angular is a Framework where React is a Library.
2. Angular has inbuild compiler(AOT) size is high normally of 5MB and they are working to reduce the bundle size, where react will have less memories.
3. End to End business applications logic can be achieved easily.where React uses Redux to achieve End to End business application logic.
4. For Angular communities support are more when compared to React.
5. Angular is two way binding and React is uni-directional.
6. Angular uses shadow DOM and React uses virtual DOM so it’s render faster compared to Angular
7. Angular uses observarble and subscribers to share the data between the components , React uses reducers to share the data between the components

ES is the community,they works on standardisation of Javascript.ES5 take care of DOM (HTML and CSS) and with the help of ES6 only Asynchronous Programs can be achieved in Javascript and ES6 is the creates the biggest evolution in Web Technologies.
