For example if there is a callback function, after running the callback function, runprocess.exit()
function Test(callback) {
callback();
return process.exit();
}
How can I prevent process.exit() execute or prevent process exit in the callback function.
You could throw an exception at the end of the callback function and catch it outside Test:
function Test(callback) {
callback();
return process.exit();
}
try {
Test(() => {
console.log('some code');
throw 'Exception';
});
} catch {}
console.log('process.exit() skipped');
