• read this paragraph of docs to see how to post code properly
• read this paragraph of FAQ to see how to find inputs for failing tests, reproduce them locally, and debug them in your IDE
• read this post for possible hint. I do not know if it's actually your issue because I cannot run your code, but that's the problem the most people miss.

Not a kata issue, all tests passed until your code timed out, there are more tests.

All tests are passed, however I am timing out? JavaScript

actually i didnt understand the kata itself?
do we need to find the number of permutation combination of the words given?

Thank you :)

Thanks for the feedback, I will try another solution.

Please use code formatting next time when you post code.

"the execution time has expired (16000 ms)" means that your code may be correct, but is too slow. Full brute force is not going to work for this one, try to think how you can optimize your code.
