Adding the p5.js library to Stackblitz IDE: A step-by-step guide

Recently, I've been using Stackblitz as my IDE to improve my coding skills on my Chromebook. While it has been effective in many ways, I have encountered difficulties when trying to integrate the p5 library. As a beginner in programming, I only grasp the fundamentals at this point.

I included the p5 dependency and added the p5.js file while linking it in the HTML code. However, I am still facing issues.

If everything was functioning properly, the draw function would continuously call itself and display the specified background and square shapes. When I attempt to invoke the function in the typical JavaScript manner, an error message pops up saying "background is not defined", indicating that the p5 library is not being executed correctly.

To effectively utilize the p5 dependency in your project, it is crucial to implement and manage it using npm. The recommended approach is to adopt the p5.js instance mode. In order to seamlessly run the code in StackBlitz post injecting the p5 dependency, your code structure should resemble the following:

import p5 from 'p5';

let sketch = (p) => {

  p.setup = () => {
    p.createCanvas(500, 500);
  };

  p.draw = () => {
    p.background(220);
    p.fill(120);
    p.rect(50, 50, 100, 100);
    console.log("Greetings! 1")
  };

  console.log("Greetings! 2")
};

let myp5 = new p5(sketch);

It is important to note that when utilizing a p5 function in instance mode, you must invoke it as a method of the p object (or any other chosen name), while native JS methods can be called conventionally.
