3,276 PointsWhich method should I use in object . vs []
Why couldn't I do that: namesActions.action() instead of namesActionsaction;
What is the difference between both and when should I use one instead of the other.
I mean the square brackets vs the dot.

231,236 PointsFor code formatting, you can use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. 
But here's the difference between those statements:
-
namesActions.action()this calls a method named "action"
-
namesActions[action]()
So if you had action = "test"; then doing the second one would be the same as namesActions.test().

231,236 PointsThat's right. The value of the term in the brackets will be used as a property (or method) name.
