Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
ESLint
- Slow performance on large codebases compared to newer tools like Oxlint and Biome
- Complexity in configuration from scratch, particularly for TypeScript support
- Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features
Yarn
- Yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects
- Smaller ecosystem and community compared to npm, though still substantial

Answered from the vendors’ own pages
ESLint: Does ESLint automatically fix code issues?
Many problems ESLint finds can be automatically fixed via the --fix flag. ESLint fixes are syntax-aware so you won't experience errors introduced by traditional find-and-replace algorithms.
SourceYarn: What is Yarn's main advantage over npm?
Yarn downloads packages in parallel, significantly reducing installation time. It uses a yarn.lock file for deterministic installs, ensuring identical package versions across machines and preventing version conflicts common with npm.
SourceESLint: How much does ESLint cost?
ESLint is completely free and open-source software maintained by the OpenJS Foundation. The project accepts voluntary donations from sponsors.
SourceYarn: Can I use Yarn in offline environments?
Yes, Yarn supports secure offline environments. The yarn.lock file enables reproducible installs without requiring new downloads.
SourceESLint: Can I write custom ESLint rules?
Yes. You can develop custom rules that work alongside built-in functionality through ESLint's plugin system, allowing complete customization for your project needs.
