Hey @Shielagaa,
Happy to shed some light on that dollar sign you encountered! It can be a bit confusing if you haven’t seen it before.
The $ in javascript meaning is quite simple in this case! It’s a shorthand for jQuery, which is a popular JavaScript library. When you see $(), it’s a function that helps you easily select HTML elements, like document.querySelector(), but with a lot more functionality built in.
In your example, $(document).ready() is just a way of saying, “Wait until the document is fully loaded before running the function.”
Hope this clears things up for you!
