+### Modules loaders
+
+Node.js has two system for resolving a specifier and load modules.
+
+There is the CommonJS module loader:
+
+* It is fully synchronous.
+* It is monkey patchable.
+* When resolving a specifier, if no exact match is found, it will try to add
+  extensions (`.js`, `.json`, and finally `.node`).
+* It supports [folders as modules][].
+* It treats `.json` as JSON text files.
+* `.node` files are interpreted as compiled addon modules loaded with
+  `process.dlopen()`.
+* It treats files that do not have `.json` or `.node` extension as JavaScript
+  text files.
+* It cannot be used to load ECMAScript modules. Attempting to do so will result
+  in a [`ERR_REQUIRE_ESM`][] error.
+* It can be accessed using `require` function.
+
+There is the ECMAScript module loader:
+
+* It is Asynchronous.
+* It is not monkey patchable, can be customized using [loader hooks][].
+* No extension searching, the specifier must point to the exact URL of the file.
+* It does not support folders as modules.
+* Import assertion are needed to load JSON modules (behind
+  `--experimental-json-modules` flag).
+* It only accepts `.js`, `.mjs`, and `.cjs` extensions for JavaScript text
+  files.
+* It can be used to load (JavaScript) CommonJS modules. It passes the module
+  content through the `es-module-lexer` to assess what are its exports, convert
+  its URL to an absolute path and load it using the CommonJS module loader.
+* It can be accessed using `import`.
