Once
6,034 of 6,172osuushi
Description:
You'll implement once, a function that takes another function as an argument, and returns a new version of that function that can only be called once.
Subsequent calls to the resulting function should have no effect (and should return undefined).
For example:
logOnce = once(console.log)
logOnce("foo") // -> "foo"
logOnce("bar") // -> no effect
