What is different between ES5 vs ES6

Es stand for ECMAScript (European Computer Manufacturers Association)

ES5 and ES6 are scripting languages mainly used in client-side scripting on www.

ES5 is a function contractors focus on how the objects are instantiated. For ES5 you have to write function keyword, and return, to be used to define the function, like normal general javascript language.

ES6 class allows the developers to instantiate an object using the new operator, using arrow function, incase ES6 doesn’t need to use function keyword to define the function, also return keyword can be avoided to fetch the computer value.
