use $(document).ready() to ensure the page is ready to be manipulated.

.ready() can take arg such a functions

$('some element') creates a js object that you can do something with or manipulate in some way

note that you must create a js object of a dom element to call jquery methods on it

the methods you can call on these objects are either getters or setters

getters gets info on the selection 

setters alter the selection

Chaining is possible because every setter method in jQuery returns the selection on which it was called
