filter water - GADGET
The filter () method creates a new array with all elements that pass the test implemented by the provided function. Also, use typeof operator in order to find out the type of item from array. 3 If being able to filter multiple elements is important, how about using reduce to iterate over the array and sort them into filtered and unfiltered categories.
Context Explanation
This has the upside of not iterating over the array more than once before processing the results. I find the list comprehension much clearer than filter + lambda, but use whichever you find easier. There are two things that may slow down your use of filter. The first is the function call overhead: as soon as you use a Python function (whether created by def or lambda) it is likely that filter will be slower than the list comprehension.
