Is there any method for converting String into Number?

Question

Javascript

I am a beginner, and I have a problem with 1 task;

let numbers='1.54,4.005,6,2.1,3.50';

I am trying to create an array where I will push these strings as numbers, to get array like this;

array=[1.54, 4.006, 6, 2, 1, 3.50]; I tried several methods; parseInt, numbers*1, Number(numbers). but it does not work. Please assist.

`const array = numbers.split(',').map(n => Number(n))` should do it. (Or the shorter, but less obvious form of `.map(Number)` instead of `.map(n => Number(n))` - but this won't work with everything, it just "happens" to work with `Number` because it looks only at a single argument.) — CherryDT, Jun 22 '22 at 20:04
Thanks :) Nope, it is not working, , Result: [ 1, NaN, NaN, NaN, 50 ] — Katerina, Jun 22 '22 at 20:08
What do you mean? You can [see here](https://jsfiddle.net/qn65oxd2/) that it works. Please include the full code that's failing for you in your question, ideally as runnable snippet so we can see it live. — CherryDT, Jun 22 '22 at 20:09
My bad, I incorrectly put "." instead of ",", thank you so much :)) It is working now <3 — Katerina, Jun 22 '22 at 20:13

You can split the string on commas to create an array, then use Array#map to convert each element. The unary plus operator, parseFloat, or the Number function can convert a string to a number.

let numbers='1.54,4.005,6,2.1,3.50';
let res = numbers.split(',').map(x => +x);
console.log(res);

Split the string into an array of strings, then use Number on each item with Array.map

numbers.split(',').map(Number);
