To trim all strings in an array use the `map()` method to iterate over the array and call the `trim()` method on each array element.
Now, the flatMap method gets invoked in the chain of calls, and the use is to perform processing and transform the stream passed. The flatMap method takes a Function as its parameter. The method applies transformations over the elements and flattens the result. In this case, Collection::...
well kind of - or Yet another way you can use Symbols The "kind of" is probably the most important part... It's not rare to see people complaining about how scarce javascript's standard lib is. I mean, even a basic method like Array's flatMap was added only recently. So it seems...
