 Notes:
-* The `COMMAND` will not run if the compilation failed.
-* The child process (`COMMAND`) will be terminated before creating a new one.
+* The (`onSuccess`) `COMMAND` will not run if the compilation failed.
+* Any child process (`COMMAND`) will be terminated before creating a new one.
 * `tsc-watch` is using the currently installed TypeScript compiler.
 * `tsc-watch` is not changing the compiler, just adds the new arguments, compilation is the same, and all other arguments are the same.
 * `tsc-watch` was created to allow an easy dev process with TypeScript. Commonly used to restart a node server.
