What does the comma operator do in JavaScript? (5 answers)

Closed 7 years ago.

我读了。

var global = (function(){ return this || (0||eval)( this ); }());

之后是 minised:

l=function(){return this||(0,eval)("this")}();

因此,<代码>(0,eval)?

我在 Chrome星座、(0,1)、(2,1)、(2,{})、2,1等中发挥了作用,始终如一。

Even though I have no idea the purpose of (0||eval)... (0,eval) is the equivalent and one less character.
