This crate provides functionality for extracting and processing scope information from JavaScript source files,
and resolving that scope via SourceMaps.
# Features
- Extracting scopes from source text using [`extract_scope_names`]
- Fast lookup of scopes by byte offset using [`ScopeIndex`]
- Fast conversion between line/column source positions and byte offsets using [`SourceContext`]
- Resolution of minified scope names to their original names using [`NameResolver`]
