 # ## Do these functions work outside of TidierData.jl?
 
-# Yes, both `if_else()` and `case_when()` work outside of TidierData.jl. However, you'll need to remember that if working with vectors, both the functions and conditions will need to be vectorized, and in the case of `case_when()`, the `=>` will need to be written as `.=>`. The reason this is not needed when using these functions inside of TidierData.jl is because they are auto-vectorized.
