Mixing sync and async flows

[antonioaltamura]

I'm aware Cypress functions run asynchronously, despite the fact the two cy.get here would run in sequence:

cy.get(selector).then($res => {
   console.log($res)
})
cy.get(selector)
[...]

I've always found this a bit confusing, but this is another story :).
The question is: I want to write a utility function to check whether I have results or not in a table.
It is not an assertion, I need the function to return a boolean here (for subsequent tests IFF I have results).

export const hasResults = gridSelector => {
    cy.get("table > tbody > tr")
        .then($rows => {
            if ($rows.length) {
                return !Cypress.$($rows[0]).hasClass("no-results")
            }
        })
}

Of course, the code above won't work because cy.get is async. Is there an easy and compact what to write such a function?

It seems all works fine just by returning cy.get

export const hasResults = gridSelector => {
    return cy.get("table > tbody > tr")
        .then($rows => {
            if ($rows.length) {
                return !Cypress.$($rows[0]).hasClass("no-results")
            }
        })
}

and then consumer-side this

hasResults("opencga-family-grid").then($result => {
    console.log(result)
})

I'm going to leave the discussion here, it could be useful to someone else, or in case someone wants to add related information.
