when reading logs, JSON changes from double quotes to single quotes - json

Question

With the apache logs (below) I'm able to parse out a JSON:
[2014.02.14_21.24.22.543] other info I don't care about json: {
"petstore": "store_number_8",
"dogs":{
"terrier":{
"total":2
}
},
"cat":{
"siamese":{
"total":5
}
}
}
1) Is this valid JSON? 2) Why would the double quotes be turning into single quotes?
After I read it in, parse out the JSON, and display it I get the following:
{
'petstore': 'store_number_8',
'dogs':{
'terrier':{
'total':2
}
},
'cat':{
'siamese':{
'total':5
}
}
}
Btw, I'm using Node.js' fs.createStream to read in the logs, then simply doing a console out (so far I'm not doing any sanitization and eventually I will be writing it to a file).
fs.creatReadStream(logs).pipe(split()).on(data, function(line){
if(line.match(/json\:/)){
shouldThisBeValidJSON = JSON.parse(line.slice(line.indexOf('{'), line.length));
console.log(shouldThisBeValidJSON);
}
Thank you in advance.

console.log doesn't return JSON. It returns human-readable representation of this object.
So no, it's not JSON, it's something closer to JSON5.
If you want JSON to be displayed, you have to pass a string to console.log, i.e. console.log(JSON.stringify(shouldThisBeValidJSON))
