Use Case Suggestion: thousandSeperator

function thousandSeperator: Seperate thousands using commas

const thousandSeperator = (num) => {
    let parts = num.toString().split(".");
    parts[0] = parts[0].replace(/\B(?=(\d{3})+(?!\d))/g, ",");
    return parts.join(".");
}

console.log(thousandSeperator(130000));
//=> 130,000

Thanks @jadjoubran 😊

yes indeed, the problem is if you take a look at this example:

const flattenDepth = (arr, depth = 1) =>
  depth != 1 ? arr.reduce((a, v) => a.concat(Array.isArray(v) ? flattenDepth(v, depth - 1) : v), [])
  : arr.reduce((a, v) => a.concat(v), []);

you can immediately understand what the function does but reading what’s happening inside the function takes a lot more time

And awesome thanks 😄

Not necessarily one liner solutions, for example How to fetch json in JavaScript and other use cases are more than one line, however they’re tackling a single use case, rather than a ready made function.

The reason why I’m avoiding functions is because 30-seconds-of-code has most of these covered
