body: <pre><code>   e = '[{lat:-34.92967677667683,lng:-62.34831333160395},{lat:-34.93002861969753,lng:-62.360866069793644},{lat:-34.93526211379422,lng:-62.36063016609785},{lat:-34.93571078689853,lng:-62.35996507775451},{lat:-34.935798629937075,lng:-62.34816312789911},{lat:-34.9333358703344,lng:-62.34824895858759},{lat:-34.9320340961022,lng:-62.348334789276066}]'
  </code></pre>
  <p>I want to replace <code>lat</code> with <code>&quot;lat&quot;</code> and <code>lng</code> with <code>&quot;lng&quot;</code>.
  However, this does not work:</p>
  <pre><code>e.replace('lat', &quot;lat&quot;)
  </code></pre>
