js returning faluse via function but its getting undefined

It is difficult to provide a specific answer without seeing the code you are working with. However, if a function is returning false but is being evaluated as undefined, it could be due to the function not being called properly or not returning a value at all.

Make sure that the function is being called with the correct parameters and that there are no syntax errors. Additionally, ensure that the function is actually returning a value and not just executing statements without returning anything.

If you are still having issues, try debugging your code by using console.log statements to track the flow of data through your function. This will help you identify any errors or unexpected behaviors.
