How to access a quoted property in javascript?

Question

Here is a object declaration: var o = {"foo-bar": 24} Then, my question is how to access the property?

I forget it that I can access a object's property by using square brackets...

I think this question must be there in this week's "Stack Overflow Weekly Newsletter" mail. — codeVerine, May 30 '13 at 09:37
I just thought in a java programming way. I just tried to access the property in a java convention... — YON, May 30 '13 at 09:37
