Tests whether the key set of the dictionary contains the expected keys. If strict is set, extra properties are not tolerated, the dictionary provided must have exactly the expected keys. Example A:

1. { "first": 1, "third": 3, "fifth": 5 } @0 received via dict

2. ["first", "fifth"]@0 received via expected keys

3. strict is set to false

4. has sends true@0

Example B:

1. { "first": 1, "third": 3, "fifth": 5 } @0 received via dict

2. ["second", "seventh"]@0 received via expected keys

3. strict is set to false

4. has sends false@0

Example C:

1. { "first": 1, "third": 3, "fifth": 5 } @0 received via dict

2. ["first", "fifth"]@0 received via expected keys

3. strict is set to true

4. has sends false@0
