The use() clause in PHP closures might seem annoying at first, but it actually helps enforce referential transparency in your functions.

Ah, you are right. I have not used that method of creating objects in a long time and completely forgot about it. Thanks.

One thing I do like about the “use” syntax is that it is easier for the parser to see what variables are being used in the closure. I know JavaScript minification programs have a lot of bugs that stem from the fact that it is hard to tell what the closure is using sometimes.

A small correction on “Now JavaScript does not have traditional classes like PHP”. Javascript does have objects you can instantiate and save state with, but most of the time its not needed and we use static objects instead (var obj = {}). Example:

function Object(param) {
function Object(param) {
// Private constructor
};

this.publicVar = param;
this.publicMethod: function() {};

var privateVar;
function privateMethod() {};
}

var obj = new Object(1);

However back onto the topic at hand. The use() in the closure really irks me sometimes as I really wish it would just inherit the current scope, but oh well.
