title: How can I convert string to array in JavaScript?
body: <p>Here is my string.</p>
  
  <pre><code>[('hxe718a186f56f9330368d69a6f47b459427a16a17', 3), ('hx08737510fbd9eaa5182354eb826a8ce84f659ab1', 1), ('hx579250b23b1bcc809da119182bc0b8421922701f', 7), ('hx0deffb4c44da662a9b36008a5ccd3e2ef704e803', 3)]
  </code></pre>
  
  <p>I want to convert this string to array or JSON.</p>
  
  <p>var arr = <code>"Some works that covert string to array or JSON"</code></p>
  
  <p>So I want to get the result like bottom.</p>
  
  <p>arr[0] = > ('hxe718a186f56f9330368d69a6f47b459427a16a17', 3)</p>
  
  <p>arr[1] = > ('hx08737510fbd9eaa5182354eb826a8ce84f659ab1', 1)
  ...</p>
  
  <p>Is there any way to do this? I can't find the way.</p>
