Merge the throw new Error statement with await in a single expression

Question

Merge the throw new Error statement with await in a single expression

Is it possible to combine throwing an error and using the await keyword in one statement using the AND operator? The code snippet below demonstrates my intention:

throw new Error() && await client.end()

.

So far, this approach has been working well. However, I'm wondering if there are any potential issues with this method and whether there might be a better way to write it.

The primary goal here is to close the Database connection while also triggering an error.

Answer №1

When dealing with scenarios like this, I believe the finally block is the most suitable solution. Take a look at it on the Mozilla documentation here. In your specific situation, the implementation would look something like this:

try {
    // code that may result in an error
} catch {
    // manage the error scenario
} finally {
    // regardless of what happens, close the connection
    await client.end()
}

Alternatively, if you prefer to keep the connection open in the absence of errors, you can simply move the closing line into the catch block:

try {
    // code that may result in an error
} catch {
    // manage the error scenario
    await client.end()
}
