Poor Man's JQuery
What it lacks in flexibility and versatility, it makes up for in brevity.
function $(id) {
return document.getElementById(id);
}
...from slide 44: coding while you commute
And here's the slightly less-poor poor man's jquery, updated for browsers in the modern age....
function $(selectors) {
return document.querySelectorAll(selectors)
}
Note that this returns an array of elements.
