JSON

• data types to represent multiple values:
  • arrays:
    • like an unnamed list in R
    • written with []
    • e.g. [null, 1, "string", false]
  • objects:
    • like a named list in R
    • written with {}
    • the names (keys in JSON terminology) are strings, so must be surrounded by quotes
    • e.g. {"x": 1, "y": 2}
