Dictionary: JQuery: a javascript file that one includes in webpages. It lets you find elements using css style selectors and then do something with the elements using jquery methods

Multiple elements: if a selector returns several elements, the object contains reference to each element ex. ${'li'}

Set Information: if a jquery selection holds more than one element, and a method is used to update info on the page, it will update all of the elements in the matched set, not just the first one.

Chaining: the process of placing several methods in the same selector

implicit iteration: the ability to update all of the elements in the jquery selection
