NoBracketNotationForObjects

Observed

Correction

Here is what's right.

One can have access, to read or to modify, the properties of an object with two different notations:

• dot notation, e.g. obj.field_name
• bracket notation, e.g. obj["fieldname"]

Origin

Where could this misconception come from?

Students might be familiar with the square bracket notation for accessing elements inside arrays and thus believe that the syntax is limited to arrays.
