$

$(selector, node?) is shorthand for querySelector. The element type is inferred from the selector's leading tag, so $('input[name="x"]') typechecks as HTMLInputElement | null. Pass an explicit type parameter to override, e.g. $<HTMLDivElement>('.my-class'). For the all-matches array see $$. Part of pota/use/test.

Arguments

Argument Type Description
selector string A CSS selector passed to querySelector.
