I want to run a js file that I wrote myself

[Guo-yyds]

I have two questions: Question one: What is the relationship between this and spidermonkey? What is the structure of this project that I see mainly in the test section consisting of wasmtime + wasmtools? What does this have to do with spidermonkey? Question two: I want to run a js file that I wrote myself. How do I do it? tests is too confusing
