In ECMAScript 2015 , also known as ES6 , many new features were introduced. One of the feature which get introduced was “Arrow Functions”.
/********* Traditional way *************/
var func1 = function old(x,y) {
return x+y;
}
/************* New way ***************/
var func2 = (x,y) => {
return x+y;
}
If the function’s body has only the return statement
var func3 = (x,y) => x+y;
var func4 = (x) => x*1;
The Arrow functions can be invoked like normal functions
func1(1,1); // Output 2
func2(1,1); // Output 2
func3(1,1); // Output 2
func4(3); // Output 3
