title: How to execute a JavaScript function when I have its name as a string
body: <p>I have the name of a function in JavaScript as a string. How do I convert that into a function pointer so I can call it later?</p>
  
  <p>Depending on the circumstances, I may need to pass various arguments into the method too.</p>
  
  <p>Some of the functions may take the form of <code>namespace.namespace.function(args[...])</code>.</p>
