JavaScript !function(){}
function, javascript, sizzle
Solution
!function(a){/* ... */}();
Using an unary operator to invoke an IIFE is common practice. That's a common shorthand for:
(function(a){/* ... */}());
or:
(function(a){/* ... */})();
You can also substitute the not unary operator with any other unary operator:
-function(a){ /* ... */ }();
+function(a){ /* ... */ }();
/* ... etc. */
Problem
when looking at the minified Sizzle code, I noticed that it begins like this: ``` !function(a){//... }(window) ``` Why is there an exclamation point at the beginning? I thought that `!` was the `not` operator. Thank you. Edit: Full Code.
