How to divide number and string from string array?

Question

I have a question.

If I get "10S2D*3T" string, I have to divide number and not number like that.

What I want to do

INPUT

"10S2D*3T"

OUTPUT

[10, 'S', 2, 'D','*',3,'T']

It's my result

function solution(dartResult) {
    var answer = 0;
    var point = dartResult.split(/\D/gi);
    var option = dartResult.split(/\d/gi);
    console.log(point);
    console.log(option);
    return answer;
}

console.log(solution("10S2D*3T"));

Use the match method. Also your description is unclear since D and * are not numbers and are separated in the result. — Casimir et Hippolyte

What do you mean by "divide number" ? You want to extract the number from the input string ? You want to perform a division ? By the way, what is the meaning of "S", "D", "T" and "*" ? We need more context in order to provide accurate answers. — user1636522

You can use string split method and pass it a regular expression to check for digits and filter the array of empty strings.

var regExp = /(\d*)/;
var output = '10S2D*3T'.split(regExp).filter(Boolean);

output will be:
["10", "S", "2", "D", "*", "3", "T"]

You should explain why you put the capture group in the regular expression. That's the important thing he was missing in his code.

capture group is for checking any number of digits in sequence.
