When in a monorepo, why does TypeScript append to the start of a path?

edit

TypeScript appends to the start of a path in a monorepo to differentiate between packages and modules that may have the same name. By adding a prefix to the path, TypeScript can accurately identify the correct package or module to import or reference. This is necessary in a monorepo setup where multiple packages and modules are sharing the same codebase and may have overlapping names. Without the prefix, TypeScript may mistakenly import the wrong package or module.
