Question

Is there anything in javascript that is the equivalent of java static imports? For example, if I have a Math class that looks like

com.example.Math = function() {

   function1(...) {}
   function2(...) {}

}

Now some of these functions are naturally chained together such that the output to one is the input to another. I can do something like

com.example.Math.function2(com.example.Math.function1());

This is a little ugly looking, and I would really like to do something like:

function2(function1())

But I don’t want to put function1 and function2 in the global namespace. Is this possible?

Answer 1

Yes, there is. It’s called with.

with (com.example.Math) {
    function2(function1());
}

That said:

Using with is not recommended, and is forbidden in ECMAScript 5 strict mode. The recommended alternative is to assign the object whose properties you want to access to a temporary variable.

For example:

var m = com.example.Math;
m.function2(m.function1());
