This Babel plugin transforms typeof expressions, ensuring correct behavior across environments that may not fully support the Symbol primitive. It handles cases where typeof Symbol() might throw an error or return incorrect results in older JavaScript engines. By using this plugin, developers can write code that consistently identifies Symbols without encountering unexpected runtime issues, promoting broader compatibility and more reliable application behavior. It maintains expected semantics for typeof operations.
