Filter criteria are specified as the column name, followed by an equality, inequality, or Boolean operator, followed by the filter value.

I've tried the latter approach in Listing 6. (Note that filter takes a (t) : Booleanmethod, meaning it takes a single parameter of whatever type the array holds and returns a Boolean.)
