How to Remove the Last Array Element in JavaScript: 4 Ways

If you're working with arrays in JavaScript, removing the last element can be a common task. Fortunately, there are four simple ways to achieve this goal. Developers often find themselves needing to adjust the size of arrays by removing elements, and to accomplish this in JavaScript, the pop() method is widely used. This method modifies the original array by removing the last element.

However, there are other methods that do not modify the original array but rather create a new array without the last element. By using the slice() method, you can remove the last element from an array and return a copy of the array without the removed element. The spread operator and the concat() method are also helpful in removing the last element.

If you're looking for ways to manipulate arrays efficiently in JavaScript, this tutorial is a must-read. You'll learn four distinct methods for removing the last element of an array and the benefits and drawbacks of each approach. With this information, you'll be able to make an informed decision about which method works best for your situation.
