Get first and last value from array

Question

I have a an array being passed to me which is something like

var arr = ["A", "B", "C"];

What I am trying to achieve is to only get the first and last value so it should look like

var arr = ["A", "C"];

I'm not how to achieve this using splice because when I do

arr.splice(I am not sure what numbers to put here).forEach(function (element) {
        console.log(element);
});

Can someone tell me how to achieve this please.

Simply

arr.splice( 1, arr.length - 2 );

Demo

var arr = ["A", "B", "C"];

arr.splice(1, arr.length - 2);

console.log(arr);
