JavaScript convert error event to error object
export function error_fromEvent(event) {
const error = new Error(event.message, {cause: event});
if (event.type === 'error')
error.name = `${event.target.__proto__.constructor.name}Error`;

Javascript recursively get all transferables from object
// This is also a demonstration of the Z-combinator.

const Z = (f => (u => f((...x) => u(u)(...x)))(u => f((...x) => u(u)(...x))));
/* Example usage:
a = new MessageChannel().port1;
b = new ArrayBuffer(42);
my_obj = {a, x: {b, a_again: a}}
get_transferables(my_obj);
