The babel-helper-remove-or-void package is a Babel helper function used to either remove or replace a node with a void 0 expression. This utility streamlines code transformations within Babel plugins, offering a concise way to handle situations where a node needs to be effectively nulled out without introducing a dependency on undefined. It simplifies plugin logic, improving readability and maintainability for complex Babel transformations. Its primary function is to make code optimization and dead code elimination more efficient during the compilation process.
