![]() ![]() You may also define an insert method which can add an element to a specific position.Ī = function (i,elem)Īrr. The pop() method deletes the last element of an array, and returns the deleted value. "i" - array position, "." - elements to be added. ![]() ![]() It add elements to the array, and return new array. If you want to add elements to the specified position, you can use splice(i,0.) method. We know this because every array you create shares a copy of these four methods (that is because every array you create is an instance of the Array constructor). To be precise, these methods belong to the Array object’s prototype property. If you want to add an element to the array start position, use unshift() method.Īrr.unshift(13) //add 13 to the start position of array The JavaScript Array object provides four very useful methods: push (), pop (), shift () and unshift ( ). The JavaScript array index starts with zero. It returns the array length.Īrr.push(13) //add 13 to the end of arrayĪrr.push(20,30,40) //add 20, 30, 40 to the end of arrayĪlert(arr.toString()) //1,2,3,4,5,13,20,30,40 Use the Square brackets of access to array items as following below example. Array push() method adds element to the array end. ![]()
