Lesson #6

JavaScript

• This is a lightweight interpreted language
• It has first class functions
• You need to link the js file into the html file so that it runs on that page
• Where you place the script is where the file will be ran

Capabilities

• Runtime Object Construction
• Variable Parameter Lists
• Function Variables
• Dynamic Script Creation
• Object Introspection
• Source-Code Recovery

JavaScript is very different to Java language!

Variables

• NEVER use var to define a variable!
• You can declare a variable in 4 ways, var, let, const
• You can provide a value to a variable which can be: number, boolean or string
• You name your variable at the start example: let NAME_VARIABLE = BOOLEAN

Functions

• This is something that will happen when the function is called upon
