Sequential for loop
var myArray = ['First', 'Second', 'Third'];
for (var i = 0; i < myArray.length; i++) {
// Do awesome stuff here
console.log(myArray[i]);
}
Array.prototype.forEach
var myArray = ['First', 'Second', 'Third'];
myArray.forEach(function (value, index) {
// Do awesome stuff here
console.log(index, value);
})
ES6 for-of statement
var myArray = ['First', 'Second', 'Third'];
for (const value of myArray){
// Do awesome stuff here
console.log(value);
}
