I am making an eCard that has square confetti falling from the top of the canvas to the bottom and then resetting.

I got it to work with 1 confetti object, but I thought it would be nice to create an array of confetti objects so with 1 variable change(NUM_CONFETTI) I can change the amount of confetti without errors,

The error I am getting reads:

TestPC.js:265 Uncaught TypeError: Confetti is not a constructor at TestPC.js:265

The relevant lines of code are:

I'm making an eCard with falling confetti and fireworks flying up from the bottom of the screen. The logic for both are almost identical:

I make an empty array for fireworks and confetti, and then fill them with objects, using my GetRandom(mix,max) function to create each one with a random value:

I'm doing an eCard for class and I have decided to create an animation using classes for the specific objects. The first thing I am doing is trying to get the background to draw a black rectangle across the whole canvas using Background.DrawBackgound. But nothing is working.

I have tried even copy/pasting the drawing code at the bottom to get it to draw but it will not draw. I have done classes in C# before but am a bit rusty so I am thinking I have some error somewhere in how I've set up my classes.

Here's the .js:
