function bad() {
return new Promise(function(resolve) {
getOtherPromise().then(function(result) {
resolve(result.property.example);
});
})
}
If the other promise is rejected, this will happen unnoticed instead of being propagated to the new promise (where it would get handled) - and the new promise stays forever pending, which can induce leaks.
