title: difference between uglify and obfuscate? Is one more safe?
body: <p>Recently I was asked to obfuscate my javascript in order to hide a client's api key. I'm using grunt.</p>
  
  <p>Will <a href="https://github.com/gruntjs/grunt-contrib-uglify">grunt-contrib-uglify</a> obfuscate my js?</p>
  
  <p>What's the difference between uglify and obfuscate? Is one much more safe than the other?</p>
