Create a function that takes the string of words to replace, and the string to repeat until the length, then simply keep appending to a variable until the length is reached:

function replaceTextWithLength(textToReplace, replaceText) { var length = textToReplace.length; var text = ""; while (text.length < length) { text += replaceText; } return text.substring(0, length); } var words = replaceTextWithLength("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed id dui tincidunt", "sample text "); console.log(words);
