what is the advantage of arrow function 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: js arrow function
// const add = function(x,y) {
// return x + y;
// }
// const add = (x, y) => {
// return x + y;
// }
const add = (a, b) => a + b;
const square = num => {
return num * num;
}
// const rollDie = () => {
// return Math.floor(Math.random() * 6) + 1
// }
const rollDie = () => (
Math.floor(Math.random() * 6) + 1
)
Example 3: javascript arrow function
const welcome = () => {
console.log("THIS IS A ARROW FUNCTION")
}
