Linting question

[liusida]

I am new to the modern Javascript, and here is what I did to enable linting for this project.

1. git clone this repo. This is simple.
2. npm install to install all modules. There's no error, but several warnings I'll paste below.
3. npm run lint:fix to check the source code. I've got ✖ 761 problems (109 errors, 652 warnings)!
   For example, there are many errors on 'clamp' is not defined.

Did I miss any steps? I just want to setup this project in VSCode and read through and learn. Can anyone offer some insights? Thank you very much!
