Below is a variation on Example #4 that implements a multi-key natural sort on an associative array and can be called in such a way as to allow reversing the sort order and/or making the comparison case insensitive on a key by key basis. Properties that are an object constructed via new MyCustomObject(args), or built-in JavaScript types such as Date or RegExp, are not re-constructed and will appear as plain Objects in the resulting object or array. Originally published in the A Drip of JavaScript newsletter. The later is any object with a " length " property that returns the number of elements inside the object, plus numeric indices giving access to elements inside it. For a simple primary key (partition key), you must provide exactly one element with a KeyType of HASH. We use them to crunch numbers, collect objects, split strings, search, sort, and more. In standards, it is often more convenient to parse JSON into realm-independent maps , lists , strings , booleans , numbers, and nulls. Static arrays remain with fixed size throughout their life span. Every Java object created, including every Class loaded, has an associated lock or monitor.
