You can actually turn this into a utility function, like so:

async function goCatch(promise) {
    try {
        const result = await promise
        return [result, null]
    } catch (err) {
        return [null, err]
    }
}
Enter fullscreen mode Exit fullscreen mode

You could also use an object like Brendan said.

I would wrap it in a higher order function though, something that takes an async function and returns a new async function with the added catch logic

Something like this, I guess:

const safe = fn => (*args) => fn(*args)
   .then(res => [res, null])
   .catch(err => [null, err])
Enter fullscreen mode Exit fullscreen mode

Yeah. That can be way of implementing it.

Yeah. Utility function can be very helpful.
