question about querySelector

evreytime i use querySelector to get an access to an input or a button i need to first name the kind of the thing and then the class name?

for exmaple:

const descriptionButton = document.querySelector("button.description");
const addItemInput = document.querySelector("input.addItemInput");
const addItemButton = document.querySelector("button.addItemButton");
const descriptionP = document.querySelector("p.description");

u see?, lets take the descriptionButton for example. he has a class name "description" and to access it we do button.description why we cant for exmaple query this by using getElementbyClassName("description")?

You can use querySelector with just the class .description, but you need the period to indicate it is a class selector

document.querySelector(".description");
