Predicate localDefinitionOverwrites

Holds if the later definition of v could overwrite its earlier definition.

This is the case if there is a path from earlier to later that does not cross another definition of v. DEPRECATED: Use the SSA.qll library instead.

Import path

import javascript
predicate localDefinitionOverwrites(LocalVariable v, VarDef earlier, VarDef later)
