I have a code similar to this:

let requestId = 0;

function newRequest() {
    // stuff
    return requestId++; // what happens at the limit? I want wrap around.
}

I want requestId, since I want to increment to wrap around to 0 when I get to the maximum value. In C++, this is as easy as this:

auto requestId = std::uint32_t{0};

auto newRequest() -> std::uint32_t {
    // stuff
    return requestId++; // always defined behaviour, wraps around
}

I just want ++ to always be defined behaviour and wrap around. Is it possible in javascript?
