This code fails when I type-check because

crypto.subtle.digest

crypto.subtle.digest

expects a

BufferSource

BufferSource

as 2nd param, contradicting all the docs and all the examples out there:

async function digest(data: Uint8Array): Promise<string> {
    return Array.from(new Uint8Array(await crypto.subtle.digest('SHA-256', data)))
        .map((b) => b.toString(16).padStart(2, '0'))
        .join('')
}

async function digest(data: Uint8Array): Promise<string> {
    return Array.from(new Uint8Array(await crypto.subtle.digest('SHA-256', data)))
        .map((b) => b.toString(16).padStart(2, '0'))
        .join('')
}

There's nothing wrong with the code and it works just fine, but to pass typechecking I have to cast to

any

any

and silence that, which isn't great
