-Here is an example of the function's implementation.
+The `pxt::target_panic(code: number)` panic is **not** a regular function to be used. Instead, it is able to be used in the
+C, C++, and the runtime TypeScript layer.
 
+## Implementation
+In the C++ runtime, the target_panic looks like something like this.
 ``` cpp
 extern "C" void target_panic(int code) {
     DMESG("PANIC %d", code);
-    exit(1);
+    exit(1); // EXIT: this a builtin method in the C++ standard libraries, unrelated to MakeCode specific runtime functions
 }
 ```
