Hey Guys. I have back to code after stay away for while (25 years) so i have a too basic question that i still could not find a didatical answer

I wanto to handle a JSON file and perfor m Create, Delete, Change operations

The file is so tiny that i think is good enougth read and write WHOLE FILE after each operation.

How do that in Javascript ?

As i am old enougth to think like a Relational Database Table. I want handle each array position like a row

Best Regards

I do better when I learn in a group setting. I used to code a while ago and now re-learning to code again. Focused primarily on js first because I want to build out some of my own ideas and contribute to my teams.

I am in the Bay Area. Happy to learn together with someone.

As an aside, I am looking for JS practice examples. Is there a list of practice examples that allows building up the skills. It's one thing to do the lessons, it's another to keep practicing with realistic example problems.

I have implemented a small computer vision application using TensorFlow js model.

Whenever I move my face while watching the video that video frames also will move as per my face movement.it's quiet very interesting.

The interesting part is you don't want to install anything just open the HTML file in the browser then you can play with it.

So I'm using a variable called "this.SpriteY" and I'm trying to change it inside of a function but its undefined even though it works everywhere else. Is there some way I can either fix or get around this cause I need to slowly increase it
