I have the following array.
var arr = [1,0,2]; I would like to remove the last element i.e. 2.
I used arr.slice(-1); but it doesn't remove the value.

The pop() method removes (pops) the last element of an array. The pop() method changes the original array. The pop() method returns the removed element.
JavaScript pop() Method: The pop() method is a built-in method that removes the last element from an array and returns that element. This method reduces the length of the array by 1. Syntax: array.
We can use the remove() method of ArrayList container in Java to remove the last element. ArrayList provides two overloaded remove() method: remove(int index) : Accept index of the object to be removed. We can pass the last elements index to the remove() method to delete the last element.
Using del The del operator deletes the element at the specified index location from the list. To delete the last element, we can use the negative index -1. The use of the negative index allows us to delete the last element, even without calculating the length of the list.
Array.prototype.pop() by JavaScript convention.
let fruit = ['apple', 'orange', 'banana', 'tomato']; let popped = fruit.pop(); console.log(popped); // "tomato" console.log(fruit); // ["apple", "orange", "banana"] If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
