Understanding the mechanism behind how the import statement knows to navigate to the package.json file

I find myself stuck in bed at the moment, and despite numerous Google searches with no clear answers, I have chosen to seek help here.

Could someone please clarify how scoping works when using import in TypeScript and determining whether to check the package.json file? For instance, when you use import * from ‘three’, what exactly prompts TypeScript to reference the package.json for 'three'?

When utilizing the node setting for your moduleResolution, modules are required using require() just like in the context of NodeJS. The specifics of this process can be found within the provided documentation.

Referencing the details from the designated Documentation

Non-core module identifiers utilized with require() that do not start with '/', '../', or './', prompt Node.js to begin searching from the parent directory of the current module, adding /node_modules and attempting to locate the module there. It is important to note that node_modules will not be appended to a path that already concludes with node_modules.
