key differences summary

1. **iterable**:
- can be iterated over using `for...of`, `...`, or other iteration methods.
- examples: arrays, strings, sets, maps, custom iterables.

2. **enumerable**:
- properties are enumerable by default unless explicitly set to non-enumerable.
- affects how you can access object properties.

conclusion

in summary, understanding the distinction between iterable and enumerable is crucial for working with data structures in javascript effectively. use iterables ...
