@babel/plugin-transform-member-expression-literals transforms legacy member expression accesses, like foo["bar"], into dot notation, such as foo.bar. This improves code readability and can potentially lead to smaller bundle sizes. It's a core Babel plugin primarily used to modernize older JavaScript codebases by replacing bracket notation with the more concise and conventional dot notation when accessing object properties using string literals. It ensures compatibility while optimizing for cleaner code.
