Every single time you have a input text field and submit-like button next to it, at some point, you would like to bind the same action of the submit button to the press of the enter key.

It's trivial, but also it's simply better to just copy-paste it. So here its is:

function onenter(ele, f) {
	ele.addEventListener('keydown', function (e) {
		if (e.keyCode === 13) { f(e); e.preventDefault(); }
	})
}

And also while we are here, instead of using the-not-be-named lib, just use these:

function q(x) { return document.querySelector(x); }
function qa(x) { return [...document.querySelectorAll(x)]; }
function range(x) { return Array.from({length: x}, (v, i) => i); }

For more just go here.
