What is node-keese
node-keese is:
keese is a Node.js module that generates well-ordered values, appropriate for use as sorting keys.
keese can always generate a bigger value, a smaller value, and a value between two other values. This is trivial using numbers with x+1, x-1, and (x+y)/2 respectively. However, numbers have limited precision in JavaScript, so instead keese uses strings.
The string values are comparable with the builtin comparison operators (such as <), and keese can always generate a new value that satisfies the constraints (limited only by system resources).
Node.js is an event-based server-side JavaScript engine.
