how to split a string with anything that is not a number

Question

string input:

"12 apples, 3 oranges, 10 grapes"

solution:

let arr= inputString.split(" ");

issue to solve:

how would I go about splitting with anything that isn't a number?

string examples:

no spaces
- 12apples,3oranges,10grapes
numbers that are inside ()
- there are some (12) digits 5566 in this 770 string 239 (i want only 12, 5566, 770, 239)
string of numbers having math done on them
- 33+22 (should be split into 33 and 22)

what i thought could work:

arr= inputString.split("isNaN");

Why do you need to *split*? It seems like you'd want to do the exact opposite and *match* items that are *only numbers*. — VLAZ, Dec 16 '21 at 07:14

You could use a regular expression:

const str = '12apples,3oranges,10grapes';

const splitString = str.match(/(?:\d+\.)?\d+/g);

console.log(splitString);

I think the asker wants to parse an array of the numbers from the input string. – jsejcksn Dec 16 '21 at 07:24
True. Thanks for the clarity. I amended the code to reflect this. – ColourRevolt Dec 16 '21 at 07:38

let str = "12apples,3oranges,10grapes"

console.log(str.split(/[^\d]/g).filter(e => e))

str = "there are some (12) digits 5566 in this 770 string 239"

console.log(str.split(/[^\d]/g). filter(e => e))

str="33+22"

console.log(str.split(/[^\d]/g). filter(e => e))

let str = "12 apples, 3 oranges, 10 grapes"
let arr = str.match(/\d+(.\d+)?/g)
console.log(arr)
