what is foreach method in javascript

var arr = [1, 2, 3, 4, 5, 6];

    console.log(value, index, array);

// function forEach(arr, cb){  // How forEach() method works
//     for (var i = 0; i<arr.length; i++){
//         cb(arr[i], i, arr);
//     }
// }
// var sum = 0;
// forEach(arr, function (value, index, arr){
//     console.log(value, index, arr);
//     sum += value;
// })
// console.log(sum);
