4. The unshift() Method
Another
way to add an element to an array is using the unshift() method. Unlike the
push() method, this method will add an item at the beginning of an array.
For example,
var myArray = ["Kate", "Sun"];
myArray.unshift("Juliet"); //Adds "Juliet" at the beginning of the array
myArray.unshift("Libby", "Shannon"); //Adds "Libby" and "Shannon" at the beginning of the array
console.log(myArray);
Printing the array of the example above, the result would be ["Libby", "Shannon", "Juliet", "Kate", "Sun"].
