In C, in most codebases, the if(error_ok != ... and goto code is usually hidden behind some convenience macros (RET(computation_result), ENSURE_SUCCESS(comput...

When should I use Inline vs. External Javascript?
...other connection(s) and delay execution. Since this execution is basically free (as the server side is talking to the database) it must be clear that all of these jumps would cost more than doing no jumps at all.
