arrow function inside a method in javascript code example

Example 1: javascript arrow function

// Non Arrow (standard way)
let add = function(x,y) {
  return x + y;
}
console.log(add(10,20)); // 30

// Arrow style
let add = (x,y) => x + y;
console.log(add(10,20)); // 30;

// You can still encapsulate
let add = (x, y) => { return x + y; };

Example 2: javascript arrow function

let errow = () => {
  //the code you want to return;
};
Or
let errow = ('paramiter') => {
//the code you want to return
}
