A Canvas Class

• Our target for these notes.
• Our real goal is a javascript class or two.
• Class reference.
• Class syntax

  • class Name {
       local variable list
    
       constructor(params) {
          code
       }
    
       MemberFunction() {
       }
    }
            

  • Look at canvas.js
  • If a name starts with a # it is private.
    • see this reference
    • Members are not private unless declared this way.
    • Look at width vs height.
  • if get or set is before a member function name, it is a getter or setter.
  • get reference
• Create a new instance of an object with new
• By the way, this uses
  • document.createElement()
  • element.appendChild()
