The dollar symbol ($) is the most important part of jQuery.
It is used to access jQuery functions and select HTML elements.
In jQuery, the $ symbol is actually a shortcut name for the jQuery function.
Both $ and jQuery mean the same thing.
Here, the $ symbol selects paragraph elements and applies the hide method.
This is the most common way jQuery code is written.
This code works exactly the same as using the $ symbol.
The $ symbol is simply a shorter version of the jQuery function.
The $ symbol is also used to access special jQuery functions like document ready.
It ensures that jQuery runs only after the page is fully loaded.
Important Notes About $ Symbol:
- $ is an alias for jQuery
- Both $ and jQuery work the same
- $ makes code shorter and cleaner
- Avoid conflicts when using multiple libraries
