Optional type wrapper that uses proxies for
short curcuiting evaluation of deeply nested
nullable properties. This is something like
elvis operator in Swift/Kotlin/Rust where
you can write
if (a.b?.c == null) { ... }
example
type T = { x?: { y?: { z?: number } } }
const t = Optional.make<T>({});
console.log(x.y.z.valueOf()); // nullconsole.log(x.y.valueOf()); // nullconst t1 = Optional.of({
x: {
y: {
z: 10
}
}
})
console.log(x.y.z.valueOf()); // 10
