How to loop through array of objects in JavaScript(es6)

In this tutorial, we are going to learn different ways to loop through an array of objects in JavaScript.

First way: ForEach method

In es6 we have a forEach method which helps us to iterate over the array of objects.

let users = [
   {
     id:1,
     name:"king"
   },
   {
     id:2,
     name:"john"
   },
  {
    id:3,
    name:"gowtham"
  }
]

users.forEach((user)=>console.log(user.id,user.name));

// first iteration 1,"king"
// second iteration 2,"john"
// third iteration 3,"gowtham"

forEach methods takes the callback function as an argument and runs on each object present in the array.

Second way: For of loop

let users = [
   {
     id:1,
     name:"king"
   },
   {
     id:2,
     name:"john"
   },
  {
    id:3,
    name:"gowtham"
  }

]


for(let user of users){
  console.log(user.id,user.name)
}

Here we used a for of loop so that on each iteration different object is assigned to the user variable.
