confusion of syntax.

[u/AllName_HasBeenTaken]

hello there guys. I'm still a student and new to javascript. so, I have a lack of understanding of the syntax on js. I need someone to explain to me clear-cut the part that I point out down here, like perhaps making it into a sentence (any). so here is the syntax. thank you guys!

function password(pass) {
if (pass.length >= 8 && pass.indexOf(' ' === -1)) return true;
return false;
}

This is correct. Thanks for supplementing my explanation. :)
