+`module` is used to define a scoped block of code that may contain types, `let` bindings, nested modules, etc.
+
+### Example 
+
+<CodeTab labels={["ReScript", "JS Output"]}>
+
+```res
+module Point3D = {
+  type point = (float, float, float)
+  let make = (x, y, z) => (x, y, z)
+}
+
+let origin = Point3D.make(0.0, 0.0, 0.0)
+```
+
+```js
+function make(x, y, z) {
+  return [x, y, z];
+}
+
+var Point3D = {
+  make: make,
+};
+
+var origin = [0.0, 0.0, 0.0];
+```
