That's my problem with this document design/README.md.

If you don't call ref on the callback value, the callback might not return a promise and then you wouldn't be able to call p.then(...).then(...)

I try only to use "callback(value)". it would be able to call p.then(...).then(...)

Can you provide an example where it doesn't work？

p.then(() => 1) would return 1, would it not?

Of course, there is a school of thought that promises should be strict monads, in which case, the author of the callback would be obliged to wrap/lift the return value in order to satisfy the type of then (which would decompose into map and flatMap).

So p.then(() => ref(1)) would return a promise.

promise: {
            then: function (_callback) {
                let result = defer();
                let callback = function (value) {
                    result.resolve(_callback(value));
                };
                if (pending) {
                    pending.push(callback);
                } else {
                    value.then(callback);
                }
                return result.promise;
            }
        }

So p.then(() => 1) would return a promise.
