For example, when importing a closely related file, something that would be considered part of the same module (likely within the same directory), using a relative path is succinct and can document how closely related the files are. But in my experience, relative path imports are used in all cases, throughout the codebase. Babel transpiles your code at compile time. It parses all "import statements" it sees in your code. When you write something like ["a", "b"].forEach(path => { import path; }); Babel only sees 1 import statement and thereby tries to parse that statement. Except, in that translation, path has no value as it doesn't run the code, it only ... Export default. In practice, there are mainly two kinds of modules.
