-The codemod's `name` should be equal to the name of the package that you're trying to replace (which should be a package from [module replacements](https://github.com/es-tooling/module-replacements)). So if you're writing a codemod for `is-array-buffer`, the `name` of the codemod should be `is-array-buffer`.

 The `transform` function is where you can implement your codemod magic. Feel free to use whatever codemod tool you're comfortable with, [ast-grep](https://github.com/ast-grep/ast-grep), [jscodeshift](https://github.com/facebook/jscodeshift), etc. It gets passed the `file` with a `source` property which is a string containing the contents of the file, which you can use to perform transformations on. Make sure to return the changed file from the `transform` function.
