No! JavaScript has a few different Data Types;

  1. Number (1, 2, 3, 4, 5..)
  2. undefined (not yet defined)
  3. null (nothing)
  4. Boolean (true or false)
  5. String (characters within " " )
  6. Array (a set of data items seperated by comas)
  7. Objects (a series of key/value pairs of any type)

Objects can store ANY of the above data-types. Even other objects, but only arrays can store objects.
