In JavaScript, array.push() is a method that is used to add one or more elements to the end of an array. Here's a breakdown of how it works:
Syntax:
array.push(element1, ..., elementN)
array: The array you want to modify by adding elements to its end.
element1, ..., elementN: One or more elements you want to add to the end of the array.
Functionality:
The push() method appends the specified elements to the end of the array.
It modifies the original array and returns the new length of the array after the elements are added.
Example:
const myArray = [1, 2, 3];
const newLength = myArray.push(4, 5);
console.log(myArray); // Output: [1, 2, 3, 4, 5]
console.log(newLength); // Output: 5
In this example, 4 and 5 are added to the end of myArray.
newLength stores the new length of the array after the elements are added, which is 5 in this case.
So, in summary, array.push() modifies the original array by adding elements to its end, and it returns the new length of the array after the elements are added.
