There are over 4.5 billion text-enabled devices; that’s a huge potential to notify people about upcoming appointments, special events, breaking news, or commercial promotions. Sending SMS messages programmatically enables you to reach many people almost simultaneously. With Twilio Messaging you can create a Deno application that sends many messages and reports when each of them has been delivered, or not.
Twilio Messaging includes an HTTP REST API that makes it easy to interact with the SMS API. Once an SMS message request is created with the REST API, its status can be retrieved using another endpoint.
By 2012, Dahl felt the primary goal of creating a user-friendly non-blocking framework had been achieved, with Node.js having support for multiple protocols, cross-platform support, a relatively stable API, and a growing ecosystem of external modules distributed through npm.
But over time it became apparent to Dahl that a number of design decisions, like the early removal of Promises, caused problems. Security, the GYP build system, and …
Often it doesn’t matter when a Promise returns data and the members of a collection of Promises can be resolved independently without regard to timing. A function can perform asynchronous tasks that don’t depend on the data from, or the success of, other asynchronous tasks.
But sometimes business rules or program design require that asynchronous actions are dependent on other asynchronous operations. For example:
- Establishing a remote database connection must be preceded by loading configuration information from the file system.
- Performing a REST API call to a weather API must be preceded by obtaining the user’s location from …
Are you a developer looking for a new hobby that’s compatible with sheltering in place? Would you like to be able to share it with friends from a virus-safe distance?
You can stargaze from the safety of your own lawn, balcony, or roof, and you don’t need any equipment other than your own eyes, and maybe a pair of binoculars. There are plenty of bright objects in the night sky that are visible with the naked eye. One of them is the International Space Station (ISS), which is the third brightest object in the sky after the sun and moon.
The ISS whips around the earth at 27,576 kilometers per hour (17,000 miles per hour), making a complete orbit every 94 minutes. Opportunities to observe it only last a few minutes, so it’s helpful to know when the ISS will be visible and from which direction it will appear.

Reactive Extensions, known as ReactiveX, is an application programming interface (API) enabling programming languages …
You can put these skills together to retrieve remote data through an HTTP request and work with the call response asynchronously. But in doing so you’ll probably notice that code has at least one pitfall: the logical order of declared functions is reversed. That makes the code hard to read and maintain.
