Cloning a json object and changing values mutates the original object as well

Question

I was wondering why does this happen?

I have an json object stored in var myObj:

var myObj = JSON.parse(fs.readFileSync(\'json/data.json\', \'utf8\')         


        

Answer 1

You are not cloning ! :/

Replace this:

var modObj = myObj;

By this:

var modObj = JSON.parse(JSON.stringify(myObj));

If myObj is an array do this:

var modObj = myObj.slice();
