What does variable declaration with multiple comma separated values mean (e.g. var a = b,c,d;)
When I try to understand plugin codes, I often find these kind of declarations but I don't know exactly what it means.
var a = b,c,d;
Answers:
This is a syntactic shorthand, and identical to:
var a = b;
var c;
var d;
The first one (a) gets initialized with the value of b, but c and d are uninitialized.
It will define var a = b and then define var c and d
