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.
