Always in programs we declare functions and variables which then successfully use building our systems. But how and where the interpreter finds our data (functions, variable)? What occurs, when we reference to needed objects?

In this article we will discuss one more detail directly related with execution contexts. The topic of discussion is the this keyword.

This is the second part of article about object-oriented programming in ECMAScript. In the first part we discussed the general theory and drew parallels with ECMAScript. Before reading of the current part, if it is necessary, I recommend reading the first part as in this article we will actively use the passed terminology.

In this article we consider major aspects of object-oriented programming in ECMAScript.

In particular, we will consider algorithms of objects creation, see how relationships between objects (including the basic relationship — inheritance) are made, and also give accurate definitions which can be used in discussions (that I hope will dispel some terminological and ideological doubts and messes arising often in articles on OOP in JavaScript).
