title: convert single quotes to double quotes
body: <p>I have the following object:</p>
  
  <pre><code>{
    name: "TJ",
    age: 14,
    skills: {
      ruby: 14,
      html: 50
    }
  }
  </code></pre>
  
  <p>Basically I want to convert that into something like this:</p>
  
  <pre><code>{
    "name": "TJ",
    "age": 14,
    "skills": {
      "ruby": 14,
      "html": 50
    }
  }
  </code></pre>
  
  <p>So, everything should have double quotes.</p>
  
  <p>I tried to do this:</p>
  
  <pre><code>for ( let i in person ) {
     if ( typeof person[i] !== 'object' ) payload[`"${i}"`] = person[i]
     // if object then map inside and to the same
  }
  </code></pre>
  
  <p>But it failed because the output is something like this:</p>
  
  <pre><code>{
    '"name"': '"TJ"',
    ...
  }
  </code></pre>
  
  <p>Also, JSON.stringify is not good because its adding <code>"{"</code>.</p>
  
  <p>Does someone have an idea how can I achieve the ones above?</p>
