javascript - Accessing property of object with variable

If I have an object, with properties like name, phone_number, etc...how can I access those in Javascript with a variable?

I want to access the property name in javascript by doing something like this:

object {name : "bob", phone_number : "911" }
propertiesArray = ["name","phone_number"];

 object.propertiesArray[0]; // instead of  object.name;

object[propertiesArray[0]]

This will do the trick. Object attributes can be accessed like array indexes using []
