Introducing Enhanced Alert Actions and Triage Functionality
Socket now supports four distinct alert actions instead of the previous two, and alert triaging allows users to override the actions taken for all individual alerts.

Advanced tools
Package description
The es6-promise package is a polyfill for the ECMAScript 6 Promise. It provides a way to handle asynchronous operations in JavaScript by allowing you to associate handlers with an asynchronous action's eventual success value or failure reason. This lets asynchronous methods return values like synchronous methods: instead of immediately returning the final value, the asynchronous method returns a promise to supply the value at some point in the future.
Creating a Promise
This feature allows you to create a new Promise object. The constructor of Promise takes a function that takes two arguments, resolve and reject, which are functions themselves. You perform the asynchronous operation within this function and call resolve upon successful completion with the result, or reject with an error.
var promise = new Promise(function(resolve, reject) {
// do something asynchronous which eventually calls either:
// resolve(someValue); // fulfilled
// or
// reject("failure reason"); // rejected
});
Using a Promise
This feature demonstrates how to use a Promise. Once a Promise has been created, you can attach success and failure handlers to it using the .then method. The first function passed to .then is called if the Promise is resolved, and the second is called if it is rejected.
promise.then(function(value) {
// success
}, function(value) {
// failure
});
Chaining Promises
Promises can be chained, meaning that the result of one promise can be used to create another promise, forming a chain of promises. This is useful for performing a series of asynchronous operations in sequence.
new Promise(function(resolve, reject) {
setTimeout(() => resolve(1), 1000);
}).then(function(result) {
console.log(result); // 1
return result * 2;
}).then(function(result) {
console.log(result); // 2
return result * 2;
}).then(function(result) {
console.log(result); // 4
return result * 2;
});
Bluebird is a fully featured promise library with focus on innovative features and performance. It is known for its rich API and being one of the fastest promise libraries. Compared to es6-promise, Bluebird offers more utilities such as .map, .reduce, and .filter for promises, making it a more comprehensive solution for handling asynchronous operations.
Q is an earlier promise library that influenced many aspects of the Promise specification. It provides a robust set of features for creating and composing promises. While es6-promise aims to provide a polyfill for native ES6 Promises with minimalistic API, Q offers additional features like promise cancellation, better error handling, and progress notifications.

Readme
This is a polyfill of ES6 Promises. The implementation is a subset of rsvp.js, if you're wanting extra features and more debugging options, check out the full library.
For API details and how to use promises, see the JavaScript Promises HTML5Rocks article.
To install:
npm install es6-promise
To use:
var Promise = require('es6-promise').Promise;
catch
is a reserved word in IE<10, meaning promise.catch(func)
throws a syntax error. To work around this, to a string to access the property:
promise['catch'](function(err) {
// ...
});
Or use .then
instead:
promise.then(undefined, function(err) {
// ...
});
This package uses the grunt-microlib package for building.
