What is the official correct way to declare jQuery variables

Question

I am trying to learn jQuery. I keep seeing people using different methods of declaring variables.

I have seen var variable;, var $variable;, and $variable;. Which one (if any of these) is the official correct way to declare jQuery variables.

Answer 1

Declare a variable using the var keyword. Initialize using the = symbol. Example: var hText = "This is just some text." - Click on the heading to see the text displayed in the <p> elements. $(document).
