17. For each element d in lexDeclarations do
|

a. For each element dn of the BoundNames of d do
|

i. If IsConstantDeclaration of d is true, then

[...]
|
|
ii. Else,
|
|
1. Perform ! envRec.CreateMutableBinding(dn, false).
|
|
iii. If d is a GeneratorDeclaration production or a
|
|
FunctionDeclaration production, then
|
|
1. Let fo be the result of performing InstantiateFunctionObject
|
|
for d with argument env.
|
|
2. Call envRec.InitializeBinding(dn, fo).

FunctionDeclaration : function ( FormalParameters ) { FunctionBody }
|
|
|
|
1. If the function code for FunctionDeclaration is strict mode code, let
|
|
strict be true. Otherwise let strict be false.
|
|
2. Let F be FunctionCreate(Normal, FormalParameters, FunctionBody, scope,
|
|
strict).
|
|
3. Perform MakeConstructor(F).
|
|
4. Perform SetFunctionName(F, "default").
|
|
5. Return F.
