First, a sample use case:
var myArray = ['one', 'two', 'three'];
Array.prototype.a = function() {
console.log(this);
}
Array.prototype.b = {};
Array.prototype.b.c = function() {
console.log(this);
}
> myArray.a()
>> ["one", "two", "three"]
> myArray.b.c()
>> "Object"
>From the code above you can notice that:
- when "this" keyword is used inside Array.prototype.a() function then
it refers to Array.prototype object
- when "this" keyword is used inside Array.prototype.b.c() function
then it refers to Array.prototype.b object
How can I access Array.prototype inside Array.prototype.b.c() function?
When building constructor functions I could easily work around
limitated scope of "this" keyword by assigning "var self = this" at
the beginning of the constructor. Is there a simillar trick that would
allow me to alter the scope of "this" in prototypes?
