access elements using for loop js code example

Example 1: javascript loop through array

var myStringArray = ["Hello","World"];
var arrayLength = myStringArray.length;
for (var i = 0; i < arrayLength; i++) {
    console.log(myStringArray[i]);
    //Do something
}

Example 2: for loop js

let arr = [];
for(let i = 0; i <= 10; i++){
arr[i] = Math.round(Math.random() * 10);
}Result: [3, 1, 1, 2, 3, 9, 5, 6, 6, 8, 5]Or
let arr = [];
for(let i = 0; i <= 10; i++){
arr[i] = Math.trunc(Math.random() * 10);
} 
Result[7, 6, 0, 2, 4, 8, 7, 5, 5, 6, 5]
