getElementByClass ?

In JavaScript I have this from a lesson: let userName = prompt(“Please enter your name”); document.getElementById(‘userName’).textContent = userName; And this is the html: <p>Hello </p><p id = userName></p> i wanna know if i can change everything that has to do with id to class like “document.getElememtByClass” and “<p class = userName> so that I can call it whenever I want since I can’t just make multiple name ids since that’s not allowed (btw I don’t even know if any of this is possible if so pls tell me.

Yes, in JavaScript, classes are objects. This means they have properties and methods, just like any other object. The id property, however, is not a built-in property of classes in JavaScript. It's more commonly used to identify HTML elements in the DOM.

Remember that classes might be used by multiple elements. so it's plural form. 's' here v document.getElementsByClassName('yourclass'); and it returns an HTMLCollection, not a single element. https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementsByClassName

thomas642daniel I think the class in className is referring to css class, not javascript class objects...
