javascript arrow function vs normal function

Comment

// javascript arrow function vs normal function
// 0. How to code them
// 1. "this" keyword behaves differently
// 2. Arrow functions use the "argument" keyword differently
// 3. Arrow functions cannot be used as constructors (the "new" keyword)
// 4. Implicit return (arrow functions can skip the "return" keyword)

// ---- 0. How to code them
// Normal Function
let add = function (num1, num2) {
  return num1 + num2;
}

// Arrow Function
let add = (num1, num2) => num1 + num2;
// alternative if inside an object
let object {
  add: (num1, num2) => {
  	num1 + num2
  },
};

// ---- 1. "this" keyword behaves differently
var variable = “Global Level Variable”;
let myObject = { 
  variable: “Object Level Variable”, 
  arrowFunction: () => { 
  console.log(this.variable); 
  },
  regularFunction() { 
  console.log(this.variable); 
  } 
};
myObject.arrowFunction(); 
myObject.regularFunction();
// Result:
// Global Level Variable
// Object Level Variable

// ---- 2. Arrow functions cannot use the "argument" keyword
function exampleFunction() {
  console.log(arguments[0]);
  console.log(arguments[1]);
  console.log(arguments[2]);
}
exampleFunction(1,2,3)
// Result:
// 1
// 2
// 3

let exampleFunction = {
 printArguments : () => {
  console.log(arguments);
 }
}
exampleFunction.printArguments(1,2,3)
// Result:
// [x] Uncaught ReferenceError: ...

// ---- 3. Arrow functions cannot be used as constructors (the "new" keyword)
function Article(topic) {
  this.topic= topic;
}
const article= new Article('JavaScript');
// Result:
// No errors

function Article = (topic) => {
  this.topic= topic;
}
const article= new Article('JavaScript');
// Result:
// [x] Uncaught TypeError: ...

// ---- 4. Implicit return (arrow functions can skip the "return" keyword)
function exampleFunction() {
  return 10;
}
exampleFunction();
// Result:
// 10

function exampleFunction() {
  var number  = 10;
}
exampleFunction();
// Result:
// undefined

const addOne = (number) => number + 1;
addOne(10);
// Result:
// 11

Comment

function double(x) { return x * 2; } // Traditional way
console.log(double(2)) // 4


const double = x => x * 2; // Same function written as an arrow function with implicit return
console.log(double(2)) // 4
