This is the debugger of JScript. It implement the <a href="https://chromedevtools.github.io/devtools-protocol/1-2/">V8 Debugging protocol</a>,

so you can use the devtools in chrome. <br>
|

The debugger is still in early development, so please report any issues to
|

<a href="https://github.com/TopchetoEU/java-jscript/issues">the github repo</a>.

Here are the available entrypoints:
