 Objects have a linked list that contains their properties. This list actually contains property pairs, in order to save memory described in the followings:
-A property is 7 bit long and its type field is 2 bit long which consumes 9 bit which does not fit into 1 byte but consumes 2 bytes. Hence, placing together two properties (14 bit) with the 2 bit long type field fits into 2 bytes.
+A property has a one byte long descriptor, a two byte long name and four byte long value. Hence 14 bytes consumed by a property pair. Another two bytes is
+used to show the next property pair, so the total size (16 byte) is divisible by 8.
