Arrays are Amazing!!! | Learning Data Structures with CompAndCode #3

  • An array is a ‘finite, ordered set of elements’.
  • They’re denoted by [].
  • This means that the length cannot change, it’s predefined.
  • ‘Ordered’ refers to the fact that each element is indexed, starting from 0.
  • Reference items like this: arrayName[0].
  • The datatype within the array has to be the same for e.g. [“robin”, “blackbird”] (all strings).
