2. What is JavaScript?

1. Creation of JavaScript

In 1995, the Netscape Communications decided to introduce a lightweight programming language to dynamically express static HTML. So JavaScript developed by Brendan Eich.

JavaScript was mounted on Netscape Navigator 2 which is web browser of Netscape Communications, named “Mocha” in March, 1996. In September, renamed to “LiveScript” and finally named as “JavaScript” in December.

So JavaScript is now the standard programming language for all browsers. But JavaScript has not grown smoothly

1. What is Programming?

1. Computational Thinking

Programming is communication that sends commands to be performed to the computer. In order to define the “command to be performed,” the resolution task (problem/requirements) must be clearly understood, the complexity must be simply desconstructed, the data organized and sorted by modeling, and the actions arranged in sequence.

4 Fundamental of Object Oriented Programming

추상화 | Abstraction ?

  • 추상화란, 복잡한 로직을 가지고 있는 기능에서 그것을 다루기 위해 필요한 최소한의 핵심만을 추출해내는 것을 말한다. 정의만 들으면 어렵다.

    TV 전원을 예로 들어 생각해보자. 새로 산 TV의 설명서를 보면 TV를 켜려면 전원 버튼을 누르라고 되어있다. 사용자는 전원 버튼을 누르면 쉽게 TV를 켤 수 있다.

    그러나 실제로 TV의 전원 버튼을 누르는 순간 내부 전기회로에서는 복잡한 기능이 실행될 것이다. 사용자는 그것을 알 수 없고, 알 필요도 없다. TV 제작 회사에서 TV에 대한 추상화를 시켜 사용자가 쉽게 TV를 동작시킬 수 있도록 한 것이다.

  • 함수를 보통 function, routine, procedure 라고 부른다. 이 때, procedure 단위로 추상화를 하고 procdural하게 진행하는 프로그램을 절차 지향 프로그램이라고 한다. 그러나 프로그램이 거대해지고, 코드가 길어지자 프로그램을 객체(object)로 추상화하는 방법론이 나왔고 그걸 적용한 게 객체 지향 프로그램이다.
