How could I wait until a variable is initialized in Cypress?

E.g. I have the following code:

let width;
cy.get("[data-cy=foo-bar]")
  .should(element => (width = element.width()))
  .get("[data-cy=baz-baz]")
  //some other chained Cypress operations
  ...;

I would like the line .getCy("baz-baz") no to execute until the width was set. How could I achieve that in the cleanest way you know?

I would like to preserve the chaining of operations and avoid nesting, since I may require more than one variable later on and it becomes quite messy to put everything inside the should.
