 We could also have added more method calls if needed.

When chaining, the line of code could become quite long. However, jQuery is not very strict on the syntax; you can format it like you want, including line breaks and indentations.
This also works just fine:

Example

$("#p1").css("color", "red")
  .slideUp(2000)
  .slideDown(2000);
