1.

function Leak() {
  var div = document.getElementById('d');
  div.onclick = functon() { alert("hi!");  }
}

 

간단한 코드인데 IE 에서 memory leak 이 발생한다고 한다.

이걸 충분히 반복해서 실행하면 IE 가 crash 되고 만다는데...

 

2.

Programming Language Theory 측면에서 javascript 를 다시 생각해볼 필요 있음.

Week Typing, OOP, Closure, Fuctional Lanaguage 등이 키워드.

몇 가지 statement 들

  - Everything in JavaScript is Object.
  - Every object is mutable.
  - dot operator is equivalent to de-refencing by hash. ex) foo.bar === foo["bar"].
  - Functions are always closure.
