Not shown is a purely native console debugger which uses only js/src and js/jsd.
|
|
It can be found in js/jsd/jsdb. This debugger uses the JS shell and reflects
|
|
the JSD api into the JavaScript language. The actual debugger is written in
|
|
JavaScript. It can be modified and extended as it runs and can debug itself.
