//object is saved as test.jsonpack.7z

//^^^filename is automatically changed internally, from test.json to to test.jsonpack.7z

sometimes the jsonpacked versions can be larger than the unpacked versions once compression is applied. make sure to check the compressed filesizes for your data to see if jsonpack is helping or not.
`javascript
var obj = {"ok":"here is some stuff"};
var jsonPackEnabled = false;
jfc.writeFileSync("test2.json", obj, jsonPackEnabled);
//saved as test2.json.7z
var obj_decompressed = jfc.readFileSync("test2.json", jsonPackEnabled);
console.log(obj_decompressed);
//result:
//{ ok: 'here is some stuff' }
`
`javascript
var obj = {"ok2":"here is some stuff2"};
var jsonPackEnabled=true;
jfc.writeFile("test3.json", obj, jsonPackEnabled,function(err,res){
jfc.readFile("test3.json", jsonPackEnabled, function(err2,res2){
console.log("async",res2);
//result
//async { ok2: 'here is some stuff2' }
});
});
