function (){
alert("hello");
};
Run this Code
Syntax Error: function statement requires a name
function (){
alert("hello");
}();
Compose this code in bracket ( ); as any code expression can be written like c = (a+b); or c= a+b;
so,
(function (){
alert("hello");
});
Run
Output: function() ///Success
Now Run this code just after declaration using ( ); after code like-
(function (){
alert("hello");
})();
Run
Popup "hello"
So you can save memory because not defining variable name for this function....
