title: destructuring ecmascript es7
body: <p>Is there a way to simplify the following code?</p>
  
  <pre><code>let { page_size, current_page } = paging;
  
  this.p_start = page_size * current_page;
  this.p_current = current_page;
  this.p_dg_current = this.p_current + 1;
  this.p_size = page_size;
  </code></pre>
  
  <p><code>paging</code> is an object and has properties <code>page_size</code> and <code>current_page</code>. </p>
  
  <p>Is there a destructing way to assign the paging.page_size and paging.current_page directly to this.p_size and this.p_current?</p>
  
  <pre><code>  let { this.p_size = page_size, this.p_current = current_page } = paging;
  
    this.p_start = page_size * current_page;
    this.p_dg_current = this.p_current + 1;
  </code></pre>
