array loop array code example

Example 1: javascript iterate array

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 log each value
}

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

Example 2: js loop through array

// ES6 for-of statement
for (const color of colors){
    console.log(color);
}

// Array.prototype.forEach
const array = ["one", "two", "three"]
array.forEach(function (item, index) {
  console.log(item, index);
});

// Sequential for loop
for (var i = 0; i < arrayLength; i++) {
    console.log(myStringArray[i]);
    //Do something
}
