  This example demonstrates how to customize the look of JSONEditor,
  the editor below has a dark theme. Note that the example isn't worked
  out for the mode <code>code</code>. To do that, you can load and configure
  a custom theme for the Ace editor.

<div id="jsoneditor"></div>

<script>
  // create the editor
  var container = document.getElementById('jsoneditor');
  var options = {
    modes: ['text', 'tree']
  };
  var json = {
    'array': [1, 2, 3],
    'boolean': true,
    'null': null,
    'number': 123,
    'object': {'a': 'b', 'c': 'd'},
    'string': 'Hello World'
  };
  var editor = new JSONEditor(container, options, json);
