Merged multiple built-in “class” branding internal properties into a single
[[NativeBrand]] internal property
In 10.2, change environment records so that both mutable and immutable bindings
may be in an initialized state and must be initialized before use via
InitializeBinding
In 10.5 added separate algorithm for Block declaration instantiation. Block
level declaration instantiations now specified. Function and global level still
need to be updated to support let and const
Added a Declaration production to the grammar and changed StatementList to
include both Statement and Declaration
Added let and const declarations. var declarations still hoist to function
level and must not conflict with a let or const.
Hoisting and temporal dead zone for all block scoped declarations
Added semantics for destructuring binding pattern.
Added appropriate lexical scoping for declarations in bodies of switch and try
statements. Note that for statements still need work for declarations in for
head.
Added initializes for individual property level bindings in destructure binding
