+### `proc`
+
+Returns a callable function node that can be used to define expressions that can be called from other nodes. 
+
+Example:
+
+```js
+// Global constant
+const myProc = proc((a, b) => multiply(a,b));
+
+// In your component
+const style = { width: proc(10, 10 )};
+```
+
+A proc node should be declared as a global constant in your code and not recreated from inside components.
+
+It is not possible to reference nodes that are not passed as parameters.
