Subject: build-in function for obtaining the index of an element of a list

I have a question about Emacs Lisp.

Is there any Emacs built-in function that returns the index of an element
of a list?

More specifically, say I have a list

(setq lista '("apple" "banana" "orange))

then implement the function, which I want,

(functionName lista "banana")    ; => 1

If not, please give me an example of such function definition.

Thanks in advance!
