ECMA-262-3 in detail. Chapter 7.2. OOP: ECMAScript implementation.

Read this article in: Russian.

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.

ECMA-262-3 in detail. Chapter 7.1. OOP: The general theory.

Read this article in: Russian.

Introduction

In this article we consider major aspects of object-oriented programming in ECMAScript. That the article has not turned to “yet another” (as this topic already discussed in many articles), more attention will be given, besides, to theoretical aspects to see these processes from within. 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).

ECMA-262-3 in detail. Chapter 6. Closures.

Read this article in: Russian, Chinese.

Introduction

In this article we will talk about one of the most discussed topics related with JavaScript — about closures. The topic, as a matter of fact, is not new and was discussed many times. However we will try to discuss and understand it more from theoretical point of view, and also will look at how closures are made in ECMAScript from within.

The quiz

Recently some JavaScript quizzes appear then and there with the competitive titles wondering whether “you know JavaScript”? The recent quizzes were by kangax, Dmitry Baranovskiy and by Nicholas C. Zakas. All that quizzes are interesting, many questions though are mostly theoretical rather than practical.

And again just for fun, I suggest another ECMAScript quiz. I won’t use some boring things such as “a+++b”; but I will more sophisticated 😉 Some interesting questions are collected from newsgroups, mailing lists, forums and from my own.

Тонкости ECMA-262-3. Часть 8. Стратегия передачи параметров в функцию.

Read this article in: English.

Введение

В этой небольшой заметке мы рассмотрим стратегии передачи параметров в функции в ECMAScript.

В общем случае данный раздел компьютерной науки называется стратегия оценки, вычисления (evaluation strategy), т.е. свод правил для оценки и определения какого-либо выражения. Стратегия передачи параметров в функцию, является её частным случаем.
