No.

var capturedReturnValue = myFunction();

That executes the function and assigns whatever value it returns to  
capturedReturnValue.

var referenceToFunction = myFunction;

Without the () to *call* the function it will assign the function to  
the variable.

If you couldn't call functions, JavaScript wouldn't be a usable  
language.

If you want to return a function then:

function myFunction() {
	return function () {
		var something = doSomething();
		doSomethingElse(;
		return something;
	}
}
