Convert tabs to spaces, where each tab corresponds to count spaces.

• Use String.prototype.replace() with a regular expression and String.prototype.repeat() to replace each tab character with count spaces.

const expandTabs = (str, count) => str.replace(/\t/g, ' '.repeat(count));

expandTabs('\t\tlorem', 3); // '      lorem'
