Cypress commands are queued, so plain JavaScript in a test body runs before any of them

A Cypress test function does not execute commands as it runs; it enqueues them and returns, and the runner then drains the queue. Code such as let count; cy.get('li').then(els => count = els.length); expect(count).to.equal(3) always fails with count undefined, because the synchronous assertion runs while the queue is being built and the callback runs later.

Anything depending on a command's result belongs inside .then(), or in a later command, or in an alias created with .as() and read back with cy.get('@alias'). The same rule explains why branching on page state is unsafe: the condition is evaluated before the page has been queried. Cypress commands are also not promises despite being thenable, so await cy.get(...) is unsupported and mixing async/await into a test body reorders the queue in ways that are hard to debug.
