Get method value is wrong, when the value type is Map

[luozhanhong]

var NodeCache = require("node-cache");
var myCache = new NodeCache();

var map = new Map();
map.set(1, 1);
console.log(map);
// Map { 1 => 1 }

myCache.set("myKey", map, function (err, success) {
    if (!err && success) {
        console.log(success);
        // true
    }
});

myCache.get("myKey", function (err, value) {
    if (!err) {
        if (value == undefined) {
            console.log("undefined");
        } else {
            console.log(value);
            // Map {}
        }
    }
});

var myCache( { useClones: false } );

See options.

• useClones: (default: true) en/disable cloning of variables. If true you'll get a copy of the cached variable. If false you'll save and get just the reference.
  Note: true is recommended, because it'll behave like a server-based caching. You should set false if you want to save complex variable types like functions, promises, regexp, ...
