@jct117 Great work here on this solution to look up the presidents whose name includes 'James' using the filter method.
One Suggestion
-For this example, you could remove the map method because for this example you were to return an Array of objects and the filter method without the map will give you that outcome.

@jct117 Good job putting together this solution to find all of the presidents who served between 1850 and 1900. Currently, I see you have two filter method but for this example one filter is fine. when you run the second filter it ass a president who served outside of the years 1850 - 1900. Also since we are checking to see who served during this period of time you should replace president.left_office <= "1900" with president.took_office <= "1900". This will let us know if any president took office between 1850 and 1900
