JS Array Stuffy Stuff

Honestly, maybe these array methods can help me understand stack. (pushing and popping things off a stack frame, anyone?)

let numbers = [1, 2, 3, 4, 5];

push

Adds an element to the end of an array
numbers.push(6);
numbers
[1, 2, 3, 4, 5, 6]


pop

Pops the last element off of the array and returns it
numbers.pop();
6
numbers
[1, 2, 3, 4, 5]


slice

Slices off whatever you want from index x UP TO index y (slice(x, y)), and returns it.
*Doesn't change the state of the original array
numbers.slice(0, 2);
[1, 2]
numbers
[1, 2, 3, 4, 5]


splice

Deletes elements from index x for the number of places specified by y, returns the deleted element. (ie. array.splice(x, y)

numbers.splice(1, 2);
[2, 3]
numbers
[1, 4, 5]
