How to get the last item of an array and delete it from the array in JavaScript?

Question

var arr = [1,2,3,4];

I need to get the last one and then delete it from an array called arr:

var arr = [1,2,3]

This question was asked by another user, who then deleted it. Since they don't want it associated with their own account, I re-posted it so the answer is preserved. I made the question CW so I don't gain reputation from it. This is the fairest solution I could think of. — Bill the Lizard

You want to do exactly what the pop method does:

var arr = [1,2,3,4];
//...
var last = arr.pop(); // returns 4, and arr will contain now [1, 2, 3]

Can use pop method.

    var arr = [1,2,3,4];

    console.log(arr[arr.length -1]); // get the last element
    
    arr.pop(); // delete the last element
     
         (or)

    //other way for deleting the last element
    console.log(arr.splice(arr.length-1, 1));
    
    console.log(arr); // [1,2,3]
