|
When multiple like-named function declarations exist, the final is assigned
|
|
to the new binding.
|
|
info: |
|
|
[...]
|
|
9. Let declaredFunctionNames be a new empty List.
|
|
10. For each d in varDeclarations, in reverse list order do
|
|
a. If d is neither a VariableDeclaration or a ForBinding, then
|
|
i. Assert: d is either a FunctionDeclaration or a
|
|
GeneratorDeclaration.
|
|
ii. NOTE If there are multiple FunctionDeclarations for the same name,
|
|
the last declaration is used.
|
|
iii. Let fn be the sole element of the BoundNames of d.
|
|
iv. If fn is not an element of declaredFunctionNames, then
|
|
1. Let fnDefinable be ? envRec.CanDeclareGlobalFunction(fn).
|
|
2. If fnDefinable is false, throw a TypeError exception.
|
|
3. Append fn to declaredFunctionNames.
|
|
4. Insert d as the first element of functionsToInitialize.
