How to create an reusable element similar to Selenium extend elements in Cypress.io?

In Selenium, it's possible to extend elements. This makes it possible to have a set of reusable custom elements for testing.

For example, we can have a getText method added.

public static string GetText(this IWebDriver driver)
{
    return driver.FindElement(By.TagName("body")).Text;
}

And re-use it as follows:

myElement.getText();

This example is detailed here: http://www.vcskicks.com/selenium-extensions.php

Is there a way to replicate this behavior in Cypress.io? Or do we need to query and call the same methods to get the data?
