difference between normal function and arrow function

//* main difference is arrow functions do not have their own this
let user = {
  name: "HEllo world",
  functTest() {
    console.log("----functTest---", this.name) // HEllo world
  },
  arrowTest: () => { 
    console.log("----arrowTest----", this.name) // undefined
  }
}
user.functTest()
user.arrowTest()

normal function vs arrow function

// Normal Function
let add = function (num1, num2) {
return num1 + num2;
}

// Arrow Function
let add = (num1, num2) => num1 + num2;
