+We believe this new behavior is more helpful and eliminates cases where unwanted whitespace was previously added.
 
 In cases where you want to preserve the space adjacent to a newline, you can write a JS string like `{"Monkeys: "}` in your JSX source. We've included a script to do an automated codemod of your JSX source tree that preserves the old whitespace behavior by adding and removing spaces appropriately. You can [install jsx\_whitespace\_transformer from npm](https://github.com/facebook/react/blob/master/npm-jsx_whitespace_transformer/README.md) and run it over your source tree to modify files in place. The transformed JSX files will preserve your code's existing whitespace behavior.
