In order to prevent blocking behavior, the browser environment has many Web APIs that JavaScript can access that areasynchronous, meaning they can run in parallel with other operations instead of sequentially.
In this tutorial, I am going to show you exactly how you can use Async/Await with promises in an Ionic application.
If you're unfamiliar with the concept of a stack, you can imagine it as an array with "Last in, first out" (LIFO) properties, meaning you can only add or remove items from the end of the stack. JavaScript will run the current frame (or function call in a specific environment) in ...
European Computer Manufacturers AssociationScript (ECMAScript) 6 introduces a formal Promise reference type, allowing for elegant definition and organization of asynchronous behavior. Importantly, the state of a promise is private and cannot be directly inspected in JavaScript. The reason for this is ...
In this article I'll talk about a concept that is prevalent in functional programming: monads. We'll learn about JavaScript promises as well, and I'll talk about how we can learn from functional programming when developing in JavaScript. ...
DefinitionPromise: In JavaScript, a promise is an object representing the eventual completion (or failure) of an asynchronous operation. It provides a way to handle asynchronous code more cleanly and manage the results or errors that may occur when the operation completes. Promises have three ...
data object The healthcheck definition. deleteHealthcheck(version, name) ⇒ Promise Delete the healthcheck for a particular service and version. Kind: global function Returns: Promise - The response object representing the completion or failure. See: https://docs.fastly.com/api/config#healthcheck...
Monads are a funky concept that's nearly impossible to understand in all of its nuance. Maybe I'm just not smart enough. That's why I'm not going to explain any of that. Screw the mathematical definition. Look at this shit 👇 o.O wat O.o Here's a handwavy explanation in...

The overall mental shift here, for me, is that a stream -that, by definition, only ever returns one event- is not a stream; it's a Promise. But, it can certainly be converted to a stream, in the web application layer, if it needs to be integrated with stream-based workflows. In ...
