Simple function to break a sentence around a certain position without breaking the words (only at whitespaces)

breakSentenceAtPos.js

function breakSentence(sentence, len) {
	const r = new RegExp(`.{1,${len}}[^\\s]*`,'g');
	let chunk;
	let splitted = [];
	while ((chunk = r.exec(sentence)) !== null) {
		splitted.push(chunk[0].trim());
	}
	return splitted;
}

l.replace(/.{1,24}[^\s]*/g, l => a.push(l.trim()))

function breakSentence(sentence, len) {
	const r = new RegExp(`.{1,${len}}[^\\s]*`,'g');
	let splitted = [];
	sentence.replace(r, chunk => splitted.push(chunk.trim()));
	return splitted;
}
