Attempt retrieving a value in TypeScript using TryGet without non-standard type

Is there a way to implement a TryGet pattern similar to C#'s out in TypeScript?

For instance:

if(TryGetFoo(out Foo foo)
{
    Debug.Log("Got the foo, and here is it's bar: " + foo.bar);
}
else {
    Debug.Log("Can't get the foo!");
}

The idea is that the function would return a boolean while the out parameter retrieves the value/object. This eliminates the need for creating and checking a separate variable.


Currently, in TypeScript, we achieve something like this:

const foo = getFoo();

if(foo)
{
    console.log("Got the foo, and here is it's bar: " + foo.bar);
}
else {
    console.log("Can't get the foo!");
}

TypeScript can be seen as the addition of types to JavaScript.

As of now, JavaScript does not have native support for this aspect.
