![Remove Numbers From Strings
This video shows how to take multiple elements, remove numbers from each text, trim those strings, and confirm them.
cy.get(#fruit li) // jQuery Element[]
.map(innerText) // string[]
.mapInvoke(replace, /[ds]/g, ) // string[]
.should(deep.equal, [Apples, Grapes, Kiwi])
The retryable query commands cy.map and cy.mapInvoke come from my plugin https://github.com/bahmutov/cypress-map The full example is at https://glebbahmutov.com/cypress-examples Remove Numbers From Strings](https://i.ytimg.com/vi/OXiEJDjozQo/mqdefault.jpg)







![Chai Nested Property Assertion In Cypress
This video shows a lesser known Chai assertion have.nested.property The assertion works very well with objects and arrays:
cy.wrap({ name: { first: Joe } })
.should(have.nested.property, name.first, Joe)
// array example
cy.wrap([
{ sum: 42 },
{ sum: 101 },
{ sum: { errors: [Invalid operation] } },
]).should(
have.nested.property,
2.sum.errors.0,
Invalid operation,
)
