When working in C#, you have the ability to call the result of an asynchronous method synchronously by accessing the Result
property.
For example:
var returnVal = AsyncMethod().Result;
What is a similar approach in typescript?

While there is async
/await
in JavaScript, it doesn't function exactly like the Result
property in the Task<T>
class in C#. In TypeScript, the equivalent of Promise<T>
describes promise objects.
JavaScript is inherently asynchronous due to its single-threaded nature. Blocking the thread until a result arrives, as done with Result
, would halt all other code execution and potentially prevent the result from ever coming through.
Using Result
can be risky in C#, often leading to deadlocks. It's generally advised to use async
throughout instead. Similarly, in JavaScript, it's best practice to consistently embrace asynchronicity by using async/await
.
For example, instead of:
function f() {
const x = downloadSomething(); // x is a promise, I want the result
}
You should write:
async function f() {
const x = await downloadSomething();
}
By making this change, f()
now returns a promise, allowing for proper handling of asynchronicity. This aligns with best practices in both C# and JavaScript development.
