Illustrative function name

updateActiveTab has ambiguous meaning, most prominent of which doesn't mean what we are actually trying to do.

Description

updateActiveTab has ambiguous meaning, most prominent interpretation of which is not what we are actually doing in the function body.

Motivation

I know JS as server-side engineer (we have very pedantic rules on where we are allowed to change state), in this succinct but cool sample code, the flow-of-control is slightly confusing (if we don't know browser event loop) and I guess descriptive function names would reduced the confusion for new comers, the author had context and experience, but for newbies updateActiveTab would mean perhaps we are modifying something on page. Reading function def would clear the misconception, but add mental burden.
