Use splice(startPosition, deleteCount)
array.splice(-1)

Learn 4 Ways to Remove the Last Element from an Array in JavaScript | by Darius Moore | Medium
September 8, 2022 - Below, the start count (the first parameter) is given an argument of -1, and the delete count (the second parameter), is 1. These two arguments indicate that the delete operation will begin at the last element of the array, and will only delete one item, respectively. One thing to note here is that the splice method returns an array of deleted elements. If there are no items deleted from the array, an empty array will be returned.

In case you want the value of this to be the same, but return a new array with the last element removed, you can use arr.slice(0, -1) instead. The pop() method is generic. It only expects the this value to have a length property and integer-keyed properties. Although strings are also array-like, ...

Array.prototype.filter will create and return a new array consisting of elements that match the predicate.
function removeByIndex(array, index) {
return array.filter(function (el, i) {
return index !== i;
});
}
Even shorter with ECMAScript 6:
var removeByIndex = (array, index) => array.filter((_, i) => i !== index);

You can use the es6 spread operator and Array.prototype.splice
var arr = [{id:1, name:'name'},{id:2, name:'name'},{id:3, name:'name'}];
let newArr = [...arr]
newArr.splice(index)
The spread operator copies the array and splice changes the contents of an array by removing or replacing existing elements and/or adding new elements

pop() function also removes last element from array, so this is what you want(Demo on JSFiddle):
var abc = ['a', 'b', 'c', 'd'];
abc.pop()
alert(abc); // a, b, c
2 of 7

Do this
abc = abc.splice(0, abc.length-1)
Edit: It has been pointed out that this actually returns a new array(albeit with the same variable name).
If you want to return the same array, you'll have to make your own function
function popper(arr) {
arr.pop();
return arr;
}
