ClassDeclaration : class BindingIdentifier ClassTail
1. Let className be StringValue of BindingIdentifier.
2. Let value be the result of ClassDefinitionEvaluation of ClassTail with
argument className.
[...]
14.5.14 Runtime Semantics: ClassDefinitionEvaluation
21. For each ClassElement m in order from methods
a. If IsStatic of m is false, then
i. Let status be the result of performing
PropertyDefinitionEvaluation for m with arguments proto and
false.

14.3.8 Runtime Semantics: DefineMethod
MethodDefinition : PropertyName ( StrictFormalParameters ) { FunctionBody }
[...]
6. Let closure be FunctionCreate(kind, StrictFormalParameters, FunctionBody,
scope, strict). If functionPrototype was passed as a parameter then pass its
value as the functionPrototype optional argument of FunctionCreate.

7. Let result be OrdinaryCallEvaluateBody(F, argumentsList).

9.2.1.3 OrdinaryCallEvaluateBody ( F, argumentsList )
1. Let status be FunctionDeclarationInstantiation(F, argumentsList).

23. Let iteratorRecord be Record {[[iterator]]:
CreateListIterator(argumentsList), [[done]]: false}.
24. If hasDuplicates is true, then

25. Else,
b. Let formalStatus be IteratorBindingInitialization for formals with
iteratorRecord and env as arguments.

BindingRestElement : ... BindingIdentifier
1. Let lhs be ResolveBinding(StringValue of BindingIdentifier,
environment).
2. ReturnIfAbrupt(lhs). 3. Let A be ArrayCreate(0). 4. Let n=0. 5. Repeat,

c. Let nextValue be IteratorValue(next).
d. If nextValue is an abrupt completion, set iteratorRecord.[[done]] to
true.
e. ReturnIfAbrupt(nextValue).
