I knew in js I can select this -> <div id='x'>xd</div> element via document.getElementById('x') or document.querySelector('#x'), but today I discovered I can just select it writing x like it's a variable in my script already. The question is what is this method called and what is browser support?

Hah TIL: it turns out it is part of the HTML specifications
I would recommend to avoid using that feature, that could cause a lot of confusion and waste of time on a bug that is actually a feature.
Say you have declared x and given it a value, it makes it virtually impossible to retrieve the element with id x and use your own separate variable x with more likely a different meaning.
