Sort Container Array

The statement is used to sort the array item in a container. The optional key field can contain any of the escape sequences defined in Escape Sequences.

Each item in the array establishes a sort test value as follows:

• If the array item is an object; and it has an item with the specified key; and the item is a string; the string value is the sort parameter.
• If the array item is a string or number (boolean included), the item's value is the sort test value.
• If neither of the preceding is true, the sort test value is an empty string and the sort is indeterminate.

Assuming the following container array in obj:

  "genres" : [
    {
      "name" : "rock"
    },
    "blues",
    {
      "name" : "classical"
    }
  ]

executing:

Sort container array 'obj.genres' key 'name'

will result in:

  "genres" : [
    "blues",
    {
      "name" : "classical"
    },
    {
      "name" : "rock"
    }
  ]
