...in javascript, you just use the less-than and greater-than operators: let a = 'a' let b = 'b' if (a < b) { // true console.log(a + ' is less than ' + b) } else if (a > b) { console.log(a + ' is greater than ' + b) } else { console.log(a + ' and ' + b + ' are equal.') } a similar result can be achieved using the localecompare() method inherited by string instances.

A first splash into JavaScript - Learn web development
this is a method that takes two input values (called arguments) — the type of event we are listening out for (in this case click) as a string, and the code we want to run when the event occurs (in this case the checkguess() function).
...now let's look at the loop in our number guessing game — the following can be found inside the resetgame() function: const resetparas = document.queryselectorall('.resultparas p'); for (let i = 0 ; i < resetparas.length ; i++) { resetparas[i].textcontent = ''; } this code creates a variable containing a list of all the paragraphs inside <div class="resultparas"> using the queryselectorall() method, then it loops through each one, removing the text content of each.
...add the following line just below the let resetbutton; line near the top of your javascript, then save your file: guessfield.focus(); this line uses the focus() method to automatically put the text cursor into the <input> text field as soon as the page loads, meaning that the user can start typing their first guess right away, without having to click the form field first.
