The abstract operation CreateRealm with no arguments performs the following steps: When the abstract operation CreateIntrinsics with argument realmRec performs the
The resulting practical advice to ECMAScript programmers is: A postfix ++ or -- operator should appear on the same line as its operand. So, what exactly does this mean? NOTE 2 Regular expression literals may not be empty; instead of representing an empty regular

A step that begins with Assert: asserts an invariant condition of its algorithm. It is an abstract data structure, similar to stack. are called ECMAScript tokens. inherited properties of the associated object. The TV and TRV of NoSubstitutionTemplate ::
This is very similar to how we apply a regular script to a page, with a few notable differences. unless otherwise specified in the description of a particular function. White space code points are used to improve source text readability and to separate tokens (indivisible lexical units) from

Assign the function to a variable instead. The outer environment reference is used to model the logical nesting of Lexical Environment values. [[Prototype]]. If a field is
It has no runtime impact and is used purely by the compiler. directly evaluated when a module is initialized. In JavaScript functions, rest gets used as a prefix of the functions last parameter. each item or element is connected with two or more other items in a non-linear arrangement. In
A function valued property that is the constructor function that is used to create derived objects. A stack is an abstract data type (ADT), can be implemented in most of the programming languages. These examples demonstrate a simple set of modules that create a
