Emacs: Finding function definition in etags

Syntax check in js2-mode is awesome.

But sometimes I just want to define a function named "delete" or "new" even thought that's not a good idea. Js2-mode seems to treat this as an error.

How can I use build-in keywords as function name in js2-mode? I need your help.

================================================

I am sorry for my stupid question...

I'm using etags.

but writing someting like:

exports.new = function() {
};

seems etags will treat this as the definition of 'exports.new', not 'new'. 

TAGS
};exports.new248,8614

So I'm trying to write something like:

function new() {
}
exports.new = new;

How stupid I am !!!

So my questiong turn back to how to make etags find the definition of 'new', not 'exports.new' ?

Thanks. :)

"Js2-mode seems to treat this as an error"

It is an error, isn't it?

I really don't understand why you'd want to do it, but the following works:

someObject["new"] = function() {
   alert("This is the 'new' function.");
}

someObject["new"]();

Assuming someObject already exists as an object. Or:

var someObject = {
       "new" : function() {},
       "delete" : function() {}
};

someObject["new"]();
someObject["delete"]();

In the browser you can say window["new"] = function() {}, but you can't call the resulting function with new(), you have to say window["new"]().

In node.js I believe the equivalent would be global["new"] = function() {}. I don't use node, but I assume this would create a global function called "new", but you wouldn't be able to call it with the new() syntax, you'd have to say global["new"]().

I do not recommend doing this.
