Question 1

How do I disable eslint-plugin-no-loops for a specific line?

Accepted Answer

Use an inline ESLint comment like // eslint-disable-next-line no-loops/no-loops before the loop. The README shows an example for allowing exceptions in rare cases.

Question 2

What's the performance impact of using array methods instead of loops?

Accepted Answer

Array methods like map and reduce can be slower due to function call overhead, but for most applications, the difference is negligible and the readability benefits are worth it. Profile your code if performance is critical.

Question 3

eslint-plugin-no-loops vs using standard ESLint rules for loops?

Accepted Answer

Standard ESLint has rules like no-await-in-loop or no-unreachable-loop, but eslint-plugin-no-loops is stricter by banning all loops entirely. It's better for teams fully committing to functional programming.

Question 4

How to handle async operations without loops?

Accepted Answer

Use Promise.all with map for parallel async tasks, or libraries like async/await with functional patterns. This plugin encourages rethinking async logic to avoid traditional loops.

Question 5

Is eslint-plugin-no-loops suitable for Node.js projects?

Accepted Answer

Yes, it works in any JavaScript environment. However, in Node.js where performance might be more critical, consider if the functional overhead is acceptable for your use case.

Question 6

What are good alternatives to for-of loops with this plugin?

Accepted Answer

Use array methods like forEach for side effects, or map for transformations. For iterables, convert to arrays first or use libraries that support functional iteration.
