  console.log(colors[i]);
}

Example 2: javascript loop

let array = ['Item 1', 'Item 2', 'Item 3'];

// Here's 4 different ways
for (let index = 0; index < array.length; index++) {
  console.log(array[index]);
}

for (let index in array) {
  console.log(array[index]);
}

for (let value of array) {
  console.log(value); // Will each value in array
}

array.forEach((value, index) => {
  console.log(index); // Will log each index
  console.log(value); // Will log each value
});

var nums = [1, 2, 3, 5];
for (var i = 0; i,nums.length; i++){
	console.log(nums[i]);
}

Example 5: 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]
