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.
[...]
9.2.1 [[Call]] ( thisArgument, argumentsList)
[...]
7. Let result be OrdinaryCallEvaluateBody(F, argumentsList).
[...]
9.2.1.3 OrdinaryCallEvaluateBody ( F, argumentsList )
1. Let status be FunctionDeclarationInstantiation(F, argumentsList).
[...]
9.2.12 FunctionDeclarationInstantiation(func, 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.

13.3.3.7 Runtime Semantics: KeyedBindingInitialization
SingleNameBinding : BindingIdentifier Initializeropt
[...]
6. If Initializer is present and v is undefined, then
[...]
d. If IsAnonymousFunctionDefinition(Initializer) is true, then
i. Let hasNameProperty be HasOwnProperty(v, "name").
ii. ReturnIfAbrupt(hasNameProperty).
iii. If hasNameProperty is false, perform SetFunctionName(v,
bindingId).
