// async
const result = await TryAsync(async () => {
    if (condition) {
        throw new Error('failed')
        // or
        throw 'failed'
    }

    return 'succeeded'
})

// result: Either<Error, string>

if (result.isLeft()) {
    // result.value: Error

    console.error(result.value.message) // -> 'failed'
    return

console.log(result.value) // -> 'succeeded'
