So this I guess module.exports = function leftpad (str, len, ch) { str = String(str); if (ch === 0) { ch = '0'; } return Array(Math.max(0, len - str.leng

So this I guess module.exports = function leftpad (str, len, ch) { str = String(str); if (ch === 0) { ch = '0'; } return Array(Math.max(0, len - str.length)).join(ch || ' ') + str; };
