var obj = {a: "a", b: "b" /*...*/};
var string = JSON.stringify(obj);
// OUTPUT:
// "{'a':'a', 'b':'b'}"

var obj = {name: "Martin", age: 30, country: "United States"};
 
// Converting JS object to JSON string
var json = JSON.stringify(obj);
 
console.log(json);
// Prints: {"name":"Martin","age":30,"country":"United States"}

// method 2 - more readable output
