javascript arrow function callback 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; };
