Cases when Babel does not work

1. When using Babel with a non-standard or unsupported programming language. Babel is primarily designed to transpile ECMAScript 2015+ (ES6+) code into ES5 code, which is widely supported by modern web browsers. If you attempt to transpile code written in a language other than JavaScript, Babel may not work as intended.
2. When using Babel with outdated or incompatible plugins. Babel relies on plugins to handle specific language features or transformations. If you are using outdated or incompatible plugins, it can lead to errors or unexpected behavior. It is essential to keep your plugins up to date and ensure compatibility with the version of Babel you are using.
3. When encountering unsupported language features. While Babel supports most ES6+ features, there are some experimental or browser-specific features that may not be fully supported. If you rely heavily on such features, Babel may not be able to transpile them correctly, resulting in compatibility issues with certain browsers or environments.
4. When there are issues with your build configuration. Babel is typically used as part of a build process, such as with bundlers like Webpack or Rollup. If your build configuration is incorrect or misconfigured, it can prevent Babel from working correctly. It is important to ensure that your build process is set up properly and that Babel is integrated correctly into your workflow.
5. When using Babel with certain third-party libraries or frameworks. While Babel is widely compatible with various libraries and frameworks, there may be cases where conflicts or incompatibilities arise. This can occur if the library or framework relies on specific language features or code patterns that Babel does not handle correctly. In such cases, alternative solutions or configurations may be necessary.
