I am trying to solve a math problem where I take a number e.g. 45256598 % 2==0 and then split the number into separate two char digits like e.g. 45,25,65,98. Does anyone know how to split a number into individual two char digits? I Have Already Achieved this C# code but this Method I am looking in JavaScript code :-
My C# code is:-
string str = "45256598";
int n = 2;
IEnumerable<string> numbers = Enumerable.Range(0, str.Length / n).Select(i => str.Substring(i * n, n));
You can do this by using match
like this:
const splittedNumbers = "45256598".match(/.{1,2}/g)
This will return array of:
['45','25','65','98']
If you would like to split in different length, just replace 2 with the length
const splittedNumbers = "45256598".match(/.{1,n}/g)
Hope this will help you!

const numArr = [];
for(let i = 0; i < str.length; i = i + 2) {
const twoDigit = str.charAt(i) + (str.charAt(i+1) ?? ''); // To handle odd digits number
numArr.push(twoDigit);
}
let result = numArr.join(',');
console.log(result);
}

% 2? Do you only want to split your string if it's divisible by 2 (your C# doesn't seem to do that)? Is your number also a string to begin with like it is in your C# code?[...'45256598'.matchAll(/../g)].map(m => m[0]).join(',')
