How does this code optimize minification? <p>I saw some code <a href="https://gist.github.com/rma4ok/3371337">here</a> that had these variable declarations:</p> <pre><code>var equestAnimationFrame = 'equestAnimationFrame', requestAnimationFrame = 'r' + equestAnimationFrame, ancelAnimationFrame = 'ancelAnimationFrame', cancelAnimationFrame = 'c' + ancelAnimationFrame </code></pre> <p>According to a comment on the page, this is to improve minification, but I couldn't figure out how. Can someone tell me? Thanks.</p>
