Benchmark: Split into whole words

Script Preparation code:

var
  input = 'There was no possibility of taking a walk that day. We had been wandering, indeed, in the leafless shrubbery an hour in the morning; but since dinner (Mrs. Reed, when there was no company, dined early) the cold winter wind had brought with it clouds so sombre, and a rain so';

function splitText(text, maxLength = 30) { const result = []; while (text !== '') { let endIndex; if (maxLength > text.length) { // [A] endIndex = text.length; } else if (text.substring(maxLength, 1) !== ' ') { // [B} endIndex = text.lastIndexOf(' ', maxLength); } else { endIndex = maxLength; } result.push(text.substring(0, endIndex)); text = text.substr(endIndex).trim(); } return result; } console.log(splitText(input));
my answer non-destructive
function splitText(text, maxLength = 30) { const result = [], ubound = text.length; let currentPos = 0; debugger; while (currentPos < ubound) { let endIndex = currentPos + maxLength; if (endIndex > ubound) { // [A] endIndex = text.length; } else if (text.substring(endIndex, 1) !== ' ') { // [B} endIndex = text.lastIndexOf(' ', endIndex) + 1; } result.push(text.substring(currentPos, endIndex).trim()); currentPos = endIndex; } return result; } console.log(splitText(input));
