A function using async/await can use as many await expressions as it wants, and each will be handled in the same way (though a promise will only be returned to the caller for the first await, while every other await will utilize internal callbacks). A function can also hold a promise object directly and do other processing first (including ...

[18] Hooks are functions that let developers "hook into" React state and lifecycle features from function components.

A reusable asynchronous procedure is termed Actor. In the Actor model two ports are used: one to receive input, and another (hidden) port to handle the input. In Dataflow programming many ports are used, passing to an execution service when all inputs are present.
Many operating system functions exist to implement asynchronous I/O at many levels. In fact, one of the main functions of all but the most rudimentary of operating systems is to perform at least some form of basic asynchronous I/O, though this may not be particularly apparent to the user or the programmer.
Point-of-care genetic testing identifies variations in the genetic sequence at the bedside – enabling clinicians to react and alter therapy based upon the results. [ 1 ] Traditional genetic testing involves the analysis of DNA in order to detect genotypes related to a heritable disease or phenotype of interest for clinical purposes.
A narrative hook (or just hook) is a literary technique in the opening of a story that "hooks" the reader's attention so that they will keep on reading. The "opening" may consist of several paragraphs for a short story, or several pages for a novel, and may even be the opening sentence .
