I have a section in my code I don't really understand.
function nameOfFunction(a, b = null, c = null) { } what does setting the something to = null in the parameters do?

what kind of usecase would these normally be used in? if you need something to be null but not undefined?

oh I see what you're saying, use one type to determine whether a specific variable needs to be handled before running a whole function on it if it has multiple possible types
