JavaScript Array Push Method
# Introduction to JavaScript Array Push Method
JavaScript provides numerous built-in methods to work with arrays. The `push()` method is one of them and is used to add one or more elements at the end of an array. It returns the new length of the array.
The `push()` method adds the given elements to the end of an array and returns the new length of the array. This method modifies the original array and does not create a new array. It takes one or more elements as its argument and adds them to the end of the array. It can also take a single array as an argument and add its elements to the end of the original array. It is very useful when we want to add elements to an array without knowing the length of the array.
The syntax of the `push()` method is as follows:
```
array.push(element1, ..., elementN)
```
Where `element1`, `element2` etc. are the elements to be added to the end of the array.
