title: Puppeteer waitForTimeout is not a function
body: <p>I am using puppeteer in my latest project. I installed the library using NPM (npm i puppeteer). From the documentation I understood that <code>page.waitFor()</code> function was now deprecated and replaced by <code>page.waitForTimeout()</code>.</p>
  <p>When I try to use the new function I get <code>UnhandledPromiseRejectionWarning: TypeError: page.waitForTimeout is not a function</code>.</p>
  <p>What could be the possible reason? The version of puppeteer I got from NPM is 2.1.1.</p>
  <p>Thanks</p>
