In this section, we talked about arrays in JavaScript. We covered:

  • Storing data in arrays
  • Working with arrays
    • map
    • filter
    • find
    • findIndex
    • slice
    • splice
    • forEach
    • includes

This is just a small subset of the methods you can call on arrays, but they're popular and useful. To see a full list of the methods you can run, check out the documentation.
