JSON.parse()

Hi,

Have some problem with JSON.parse.

test={};
test['myname']='ESP:33FFD705-41573033-27620843';
test['first']={"pin":A15};

console.log('Orig:');
console.log(test);

json=JSON.stringify(test);

console.log('JSON:');
console.log(json);

console.log('Back:');
console.log(JSON.parse(json));

Here is the output:

Orig:
{
  "myname":"ESP:33FFD705-41573033-27620843",
  "first":{"pin":A15}
}
JSON:
{"myname":"ESP:33FFD705-41573033-27620843","first":{"pin":A15}}
Back:
undefined
=undefined

Back is undefined. I expected the same as 'test'.

Thanks
Sacha
