I am learning Mobx. when(predicate: () => boolean, effect?: () => void, options?)

As written on mobx:

class MyResource {
    constructor() {
        when(
            () => !this.isVisible,
            () => this.dispose()
        );
    }

    @computed get isVisible() {
        ......
    }

    dispose() {
        ......
    }
}

My question is that if I write as follows, do these two the same?

class MyResource {
    constructor() {
        when(
            !this.isVisible,
            this.dispose
        );
    }

    @computed get isVisible() {
        ......
    }

    dispose() {
        ......
    }
}

Have you tried? – Aleksey L. Feb 20 '20 at 07:27
One uses anonymous arrow functions the other does not – Andreas Feb 20 '20 at 07:31
Yes, I tried. It works the same. But I can not ensure. – user1471834 Feb 20 '20 at 07:34

_Might_ differ as to what `this` context `dispose()` gets. – mbojko Feb 20 '20 at 07:37
mbojko, your comment sounds reasonable. – user1471834 Feb 20 '20 at 07:39
