async-await

Vocabulary Word

Definition

'Async-await' is a neat trick in programming to help manage tasks that take unpredictable time to finish, like downloading a file. It allows the program to 'wait' on one line of code without stopping everything else it needs to do.

Examples in Different Contexts

In software development, 'async-await' is a syntactic feature of programming languages like JavaScript that allows developers to write asynchronous code that looks and behaves like synchronous code. A software developer might say, 'Using async-await simplifies handling asynchronous operations, such as fetching data from a server, by allowing us to write cleaner and more readable code.'

Practice Scenarios

Business

Scenario:

This new feature requires extensive data transfers from the cloud. We need a way to handle these transfers while keeping the application responsive.

Response:

Implementing async-await will allow us to fetch data in the background, optimizing the user interface experience.

Academics

Scenario:

While teaching you about AJAX requests, I've noticed that the students struggle when the responses arrive out of order.

Response:

Teaching them about async-await will help them understand how to successfully manage AJAX requests and their responses.
