How can I identify and resolve dependency conflicts in my `package.json`?

Dependency conflicts occur when different packages require incompatible versions of the same dependency. Use `npm ls` to view the dependency tree and identify conflicting versions. You can then try updating or downgrading specific dependencies in your `package.json` to resolve the conflicts. Tools like `npm-check` or `yarn why` can also help diagnose dependency issues. Consider using `npm audit fix` to automatically attempt to resolve known vulnerabilities and conflicts.
