I need to sort partOfArray table I need to getText , upperToCase

when do outside function I got “partOfArray is not defined”

when doing te same inside function cannot read properties of undefinied (reading each)\

it('name sorting test', () => {

    cy.visit(`${Cypress.env('res_URL')}/test`);



    const array = cy.get('#CustomerDDL').children()



        .then(function (array) {

            console.log(array)

            const shiftArray = array.map((function () { return this.label; }))



            console.log(shiftArray)

            const partOfArray = shiftArray.slice(1, 100)

        })



        .each(($option, index) => {

            partOfArray.push(Cypress.$($option).text());

            })

            .then(() => {

            const sortArray = partOfArray.sort();

            expect(partOfArray).to.equal(sortArray);

            })

})

})
