To:

sample text sample text sample text sample text sample text sample text sampl

I'am new in Javascript and I don't understand it. è_é

Please help me.

Answer 1

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);
