To insert an element at the beginning of an array, first shift all the elements of the array to the right by 1 index and after shifting insert the new element at 0th position.

Javascript How Can I Add New Array Elements At The Beginning Of An In the following example, we take an integer array and add an element to the starting of the array. we shall write a function addelement(int[] arr, int element) to return a new array with the element added to the starting of the array arr. The simplest way to achieve this is by creating a new array that is one element larger than the original, adding the new item at the start, and then copying the original array into the new one. Adding new elements at the beginning of the existing array can be done by using the array unshift () method. this method is similar to the push () method but it adds an element at the beginning of the array. Inserting an element at the beginning of an array involves shifting all existing elements one position to the right to create an empty space for the new element at index 0. examples: to know more about the implementation, please refer insert element at the beginning of an array.

Use .unshift() to add to the beginning of an array. see mdn for doc on unshift() and here for doc on other array methods. fyi, just like there's .push() and .pop() for the end of the array, there's .shift() and .unshift() for the beginning of the array. really wish we had called push append and unshift prepend. Approach: create a new array of size n 1, where n is the size of the original array. add the n elements of the original array to this array. add the new element in the n 1th position. print the new array. example: this example demonstrates how to add an element to an array by creating a new array. You can use the unshift() function to add elements to the beginning of an array. unshift() modifies the array in place, and returns new length of the array. if you need to create a shallow copy of the array and append a new element at the beginning, you have a couple of options. You can use the unshift() method to easily add new elements or values at the beginning of an array in javascript. this method is a counterpart of the push() method, which adds the elements at the end of an array. however, both method returns the new length of the array.
