title: require("lodash") - require is not defined
body: <p>I saw this lodash-thing once and thought it would be nice to use. So I try now for days, but can't get it running. Please be patient as I'm a noob in this thing.</p>
  
  <p>I have <code>npm install lodash --save</code> .. so it is in my <code>node_modules</code> and in my <code>package.json</code> I have:</p>
  
  <pre><code>"dependencies": {
  "del": "^2.2.2",
  "gulp": "^3.9.1",
  "gulp-concat": "^2.6.0",
  "gulp-notify": "^2.2.0",
  "gulp-sass": "^2.3.2",
  "gulp-uglify": "^2.0.0",
  "lodash": "^4.15.0"
  },
  </code></pre>
  
  <p>so now, when I do <code>const _ = require("lodash");</code> it should work, right?
  If not, what did I forgot?</p>
  
  <p>would be nice if someone could explain it to me. I'm watching and reading tutorials for days now, but whatever I try, I can't get it working.</p>
