Textbook: Jon Duckett: HTML & CSS

JS brings more life to a page by being able to Access Content, Modify Content, Program Rules, and React to Events
Examples of manipulations: slideshows, forms, reloading only part of a page, filtering data
Scripts are basically a series of instructions for the application/computer to execute
Start by: Defining the goal, designing the script(create a flow chart!) and then code each step

Expressions evaluate into a result with a single value
Operators dictate what calculations should occur when a programmer uses an expression
Types of Operators are: Assignment (=), Arithmetic (), *String (+), Comparison (>), and Logical(&&)

A function is a place for you to group several statements together to perform a specific task and can be reused
Always use the keyword function with a function name like “doMath”
Functions may or may not take in information, if they do, it is called a parameter
Call functions with (), Ex: doMath() / if your function used parameters you would put those values in the () like this: doMath(1,3)
Use return to get a single value from the function (usually paired with a var name) / or the return can be assigned to an array to get more than one value as a result
