Example of synchronous vs. asynchronous JS
// Old, bad, antiquated way
var value = db.synchronousRead("SELECT value");
emit(value);
// Good, asynchronous way
db.asynchronousRead("SELECT value").done(function (value) {
emit(value);
});

Parallel vs. serial independent node operations
// Serial, naive implementation
// one and two are not dependent on each other
db.read("SELECT ONE").done(function (one) {
db.read("SELECT TWO").done(function (two) {
emit(one, two);
});
});
// Parallel
var async = require("async");

Valid in JavaScript but not JSON
// quotes around keys are not required
( {key: "value"} );
// many JS parsers allow a trailing comma in a list
( [{"name": "value"},] )
