Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Extensive configuration options and plugins can be overwhelming for new users, requiring deep knowledge of Babel internals.
Babel's transformation process can introduce significant build times in large codebases, impacting developer productivity.
While Babel primarily supports JavaScript, it lacks robust support for TypeScript and other transpiled languages without additional plugins or configurations.
The official documentation may not cover all use cases comprehensively, leading to difficulties in troubleshooting specific issues.
