The article analyzes three primary causes of JavaScript dependency bloat in npm ecosystems: support for outdated runtimes, protection against global namespace mutations, and cross-realm value handling. It explains why developers rely on utility packages like 'is-string' instead of native methods, highlighting the tension between backward compatibility and modern performance. The post aims to raise awareness and encourage cleanup efforts within the community.
