Babel 6 Regeneratorruntime Is Not Defined

Have you ever come across the error message "Babel 6 RegeneratorRuntime is not defined" while working on your JavaScript project? Don't worry; you're not alone. This error often pops up when using Babel 6 to transpile async/await functions. But fear not, as in this article, we'll guide you through understanding this error and fixing it.

### Understanding the Issue:

The error message "Babel 6 RegeneratorRuntime is not defined" occurs because Babel 6 does not include the RegeneratorRuntime by default. The RegeneratorRuntime is necessary to support ES6 generators which are used when transpiling async/await functions. When Babel transpiles your async/await code, it relies on the RegeneratorRuntime functions, and if it's not defined, you'll encounter this error.

### Fixing the Error:

To resolve the "Babel 6 RegeneratorRuntime is not defined" error, you need to include the RegeneratorRuntime in your project. Here's a step-by-step guide to help you fix this issue:

1. Install RegeneratorRuntime:
You can install RegeneratorRuntime from npm using the following command:

npm install regenerator-runtime

2. Import RegeneratorRuntime:
In your project where you're using async/await functions, import RegeneratorRuntime at the top of the file:

import 'regenerator-runtime/runtime';

3. Recompile Your Code:
After adding the import statement, recompile your code using Babel to ensure the error is resolved. You should no longer see the "Babel 6 RegeneratorRuntime is not defined" error message.

### Testing Your Code:

To confirm that the error has been successfully fixed, run your code and check that async/await functions work as expected without any errors. If you encounter the error again, ensure that you have correctly added the import statement for RegeneratorRuntime.

### Conclusion:

In conclusion, the "Babel 6 RegeneratorRuntime is not defined" error can be easily resolved by including the RegeneratorRuntime in your project. By following the steps outlined in this article, you can eliminate this error and continue working on your JavaScript projects seamlessly. Remember, understanding common errors like this and knowing how to fix them is essential for mastering software development. Happy coding!
