2.3 AddValueToKeyedGroup ( groups, key, value )

The abstract operation AddValueToKeyedGroup takes arguments groups (a List of Records that have [[Key]] and [[Elements]] fields), key (an ECMAScript language value), and value (an ECMAScript language value). It performs the following steps when called:

-
  1. If groups contains a Record g such that ! SameValue(g.[[Key]], key) is true, then
    1. Assert: exactly one element of groups meets this criteria.
    2. Append value as the last element of g.[[Elements]].
  2. Else,
    1. Let group be the Record { [[Key]]: key, [[Elements]]: « value » }.
    2. Append group as the last element of groups.
 +
  1. For each Record { [[Key]], [[Elements]] } g of groups, do
    1. If ! SameValue(g.[[Key]], key) is true, then
      1. Assert: exactly one element of groups meets this criteria.
      2. Append value as the last element of g.[[Elements]].
      3. Return.
  2. Let group be the Record { [[Key]]: key, [[Elements]]: « value » }.
  3. Append group as the last element of groups.
