やる時{とき}やるじゃん！ (Yaru toki yaru jan!)

I think the meaning is something like "When you want to do something, you do
it".

Or maybe, "When you are about to do something, you just do it."

This is a positive expression?

Does it mean you have confidence in what you do? Or that you do it without
thinking first?

Thanks!

question
expressions
My friend said she says "やる時やる." a lot. What's the translation to english?
やる時はやる means "When [you/I] (really decide to) do things, [you/I] **do** them".
The nuance is that you don't just **try** to do them, you do them and do them
well.

The expression conveys that a person has the ability to do things well when
they put their minds to it, even if they are slow to act in the first place.

I think it means to get things done when necessary. Here is an example taken
from
[here](http://www.websaru.info/%E3%81%8A%E3%81%A3%E3%81%A8%E3%82%8A.html):

花子はオットリしているようで、やるときはやる人間だ。

Hanako seems quiet, but she get things done when it's necessary.
