node.js - In Sublime, why does my node process not exit naturally? -

-

when run node script in sublime 3 (as build system ... ctrl-b), if add listener stdin's data event, process stays running until killed. makes sense, since there's potentially still work do.

process.stdin.on('data', (d)=> {   // ... work `d` });

however, expected if removed listener data event, process naturally exit. doesn't!

// program never exits naturally.  function processdata(d) {   // ... work `d`, then...   process.stdin.removelistener('data', processdata); } process.stdin.on('data', processdata);

even if remove event handler after adding it, process still sticks around...

function processdata() {}  process.stdin.on('data', processdata); process.stdin.removelistener('data', processdata);

in exact case, use once() function instead of on(), doesn't clear me. missing? why stdin stream prevent process exiting, given has no listeners of kind?
