Is it valid to use && instead of if?

Question

I am using && like this and it works

typeof foo === \'function\' && foo(); //if foo exist then call it

instead

Answer 1

In the background there is a bit more with the && thingy, but for 99% of the cases it is perfectly fine to do it that way, just like this one.

Now as a personal opinion, for a one-liner I prefer it the && way instead of the if one, because I can't stand if keyword without a block below it hehe.

If you know what you are doing, linters are too picky sometimes.
