Testcafe Selector.exists doesn't return a boolean

Question

I want to do some action in case Selector('#particularButton-view').exists is true and some other action in case is false.

The problem is that it doesn't return a boolean. It returns some object. It's made to be used like this:

testController.expect(Selector('#particularButton-view').exists).ok()

How can I do to perform some action in each case?

Selector properties are wrapped in Promises, so to obtain a value you can use await from ES2017:

await Selector('...').exists;

If you can't use await, you can get the value by using then method of the promise, like:

Selector('...')
    .exists
    .then(exists => {
        If (exists)
            Foo();
        else
            Bar();
    })
