<p>The <strong>Scope</strong> class regulates lexical scoping within CoffeeScript. As you
|
||||
generate code, you create a tree of scopes in the same shape as the nested
|
||||
function bodies. Each scope knows about the variables declared within it,
|
||||
and has a reference to its parent enclosing scope. In this way, we know which
|
||||
variables are new and need to be declared with <code>var</code>, and which are shared
|
||||
with the outside.</p> </td> <td class="code"> <div class="highlight"><pre></pre></div> </td> </tr> <tr id="section-2"> <td class="docs"> <div class="pilwrap"> <a class="pilcrow" href="#section-2">¶</a> </div> <p>Import the helpers we plan to use.</p> </td> <td class="code"> <div class="highlight"><pre><span class="p">{</span><span class="nx">extend</span><span class="p">,</span> <span class="nx">last</span><span class="p">}</span> <span class="o">=</span> <span class="nx">require</span> <span class="s">'./helpers'</span>
