Another golf-style solution that doesn't abuse regular expressions 😎
const splitInParts = (s, l) => { s.split('').map((c,i) => (i+1) % l ? c : `${c} `).join('').trim(); }
Here's the less abusive solution I would actually use:
const splitInParts = (s, partLength) => { const result = []; for (let start = 0; start < s.length; start += partLength) result.push(s.slice(start, start + partLength)); return result.join(' '); }
This works because String.prototype.slice() will stop at the end of the string if the second argument index is out of bounds.
String.prototype.slice()
