Here is the deal: I am trying to read a file in JS and to affect its content to a variable I can manipulate outside the parsing function. In other words:

var content = "";
$.getJSON(dataPath, function(obj) {
    content = obj;
    console.log(content) //first log
 });
 console.log(content) // second log

I don't understand why the first log show the right content (JSon from a file), whereas the second says content is undefined.

What am I missing ?
