Description

While reviewing the application.js file, I noticed that Express defines:

var slice = Array.prototype.slice

but later in app.listen, it still uses the full property access:

var args = Array.prototype.slice.call(arguments)

This can be simplified to use the cached reference:

var args = slice.call(arguments)`

Expected Behavior

Use the already-defined slice reference for consistency and to avoid repeating

Array.prototype.slice 

The behavior remains identical.

Actual Behavior

The code currently uses the direct prototype access instead of the cached reference.

Rationale

• Improves consistency within the file

• Avoids repeated long-form prototype access

• Slight micro-optimization (cached function reference)

• No behavioral changes

• All tests continue to pass

Proposed Change

Replace:

var args = Array.prototype.slice.call(arguments)

with:

var args = slice.call(arguments)

I am happy to submit a pull request if maintainers consider this cleanup acceptable.
