OO Javascript question

Given the following

var someObject = {};

someObject.prototype.a = function() {

};

someObject.prototype.b = function() {

//How can I call someObject.a in this function?

};

How can I call someObject.a from someObject.b? Thanks.

var someObject = {};

someObject.a = function() {

};

someObject.b = function() {

//How can I call someObject.a in this function?
this.a();

};

Thanks. I actually screwed up my original question. Functions a and b are on the someObject’s prototype. I’ve tried this.a and I’m getting an error.
