Retrieving Data

We have 2 choices: bracket and dot notation

• You cannot use dot notation if the property starts with a number
someObject.1blah = INVALID
someObject["1blah"] = VALID
• You can lookup using a variable with bracket notation
var str = "names";
someObject.str = doesn't look for "name"
someObject[str]= does evaluate str and looks for "name"
• You cannot use dot notation for property names with spaces
someObject.fav color = INVALID
someObject.["fav color"] = VALID
