how to do a for loop in javascript

var colors=["red","blue","green"];
for (let i = 0; i < colors.length; i++) { 
  console.log(colors[i]);
}for (var i; i < 10; i++) {
  
}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
});const array = ['value1', 'value2', 3];

for (let i = 0; i < array.length; i++) {
  console.log(array[i]); // for i = 0, array[0] is 'value1'
}
/* console.log output:
value1
value2
3
*/
