As we already know from the second chapter concerning the variable object, the data of an execution context (variables, function declarations, and formal parameters of functions) are stored as properties of the variables object. Continue reading

Introduction

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? Continue reading

Introduction

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. You can find the first part here: ECMA-262-3 in detail. Chapter 7.1. OOP: The general theory.

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).
