My project: Program a javaScript animation according to my composition

I am advancing in my project by leaps and bounds after a very frustrating first step.
Yesterday near midnight, I succeeded in entering my composition in my Javascript program.
[(**https://editor.p5js.org/MGOBRIAL/sketches/1VZvQH6xT**)]
Today I have to calculate the times of each event of my coded composition.
I think it will be easier, I hope.
**Here are the steps I cleared**:
Compose by computer: **Musescore**
Export from Musescore to the format: **MusicXML**
Import the MusicXML file into: **Logic Pro X**
Re-export from Logic Pro X to the format: **Midi**
Import the Midi file into: Ton.js-freindly (Pars a MIDI file into Ton.js-freindly **JSON forma**t)
Copy the json structure to: **P5 JS Editor**
Saved the file: **simpleMidi-mscz-mxl-to-Projet-Acoustic Guitar.json**
Learned some bits : **JavaScript**
Write the program in javaScripte to: **translate the json structure into parameters**.
**I still have:**
Learn more javaScript : **time related function in JavaScript**
Organize musical parameters into: **musical events over time**
Choose which objects to: **select shapes based on musical parameters**
Write JavaScript Program for drawn objects to: **animate objects based on musical events over time**
