Splitting a string of numbers into an array

Question

I keep getting an error in the console that .split is not a function. Here is my code:

function addEnds(list) {

        var array = new Array();
        array = list.split(',');

        console.log(array);
    }

Basically, I want the list to equal a series of number separated by a comma, example: 1,2,3,4,5, and am trying to put those into an array. I've researched about using .split but for some reason, I'm just not getting it.

can you show how you are calling your function. split is a string method, are you calling your function like addEnds("1,2,3,4,5") ? — Jaromanda X

It’s a problem with what you’re passing as list, but you haven’t shown that. Also, you don’t need to initialize the array like that. split() will make a new array. — Mark

for now just in the console i'm typing addEnds(2,3,5,8,0); or any other random series of numbers. — lrningPrgrming

well, that's not a string ... you could try function addEnds(...list) { return list; } - or function addEnds() { return Array.from(arguments)); or even function addEnds() { return Array.prototype.slice.call(arguments);} ... those three all do the same thing on older and older browsers — Jaromanda X

It looks like the result is already split if you can call it that way. Try addEnds(‘2,3,5,8,0’) — Mark

The function shared is working absolutely fine. Just ensure that the argument that you are passing is a string.

Please follow the below fiddle:

https://jsfiddle.net/6pennzrb/

function addEnds(list) {
    var array = new Array();
    array = list.split(',');
    console.log(array);
}
addEnds("1,2,3,4,5")

const stringToArray = ([...list], delimeter = ',') => list.filter(el => el != delimeter)
const result = stringToArray('1,2,3,4,5')
console.log(result)
