+Check if a string matches the name of a Node.js builtin module.
+
+This matches based a [static list of modules](https://github.com/sindresorhus/builtin-modules) from the latest Node.js version. If you want to check for a module in the current Node.js, use the core [`isBuiltin`](https://nodejs.org/api/module.html#moduleisbuiltinmodulename) method.
+
+@param moduleName - The name of the module.
+
+@example
+```
+import isBuiltinModule from 'is-builtin-module';
+
+isBuiltinModule('fs');
+//=> true
+
+isBuiltinModule('fs/promises');
+//=> true
+
+isBuiltinModule('node:fs/promises');
+//=> true
+
+isBuiltinModule('unicorn');
+//=> false
+```
