title: file path and delete file in nodejs
body: <p>I want to delete 3 files in <code>list_file_to_delete</code> but I do not know what is the path to put to "path to three files here"?. Do I need for loop/for in/forEach function to delete all or just need a string with 3 paths likely <code>var string = "...a1.jpg, ...a2.jpg,...a3.jpg"</code>? Thanks in advance</p>
  
  <p>in <code>delete.js</code> file</p>
  
  <pre><code>var list_file_to_delete = ["/images/a1.jpg", "/images/a2.jpg", "/images/a3.jpg"]
  fs.unlink(path to three files here, function(err) {console.log("success")})
  </code></pre>
  
  <p>this is <code>myapp</code> directory      </p>
  
  <pre><code> myapp
        /app
            /js
               delete.js
        /public
               /images
                      a1.jpg
                      a2.jpg
                      a3.jpg
        server.js
  </code></pre>
