Need help with making a function return only after its inner function is called. See below for the code snippet -
function x() {
function y() {
// Inner function logic
}
return result; // This should be returned only after function y is called, which happens in another file.
}
To achieve the desired functionality, it is recommended to utilize something as a callback for b. Alternatively, employing promises can also be effective:
var promise = new Promise(function(resolve, reject) {
// execute function b
if (/* everything went smoothly */) {
resolve();
} else {
reject();
}
});
Subsequently, you can employ then to handle the fulfilled promise:
promise.then(function(result) {
return something;
}, function(err) {
console.log("Failed");
});
