The source code for express 4 (what you are making your pr for) is supposed to be es5.

[Abhishek01039]

Oh ok then which branch I should target?

[dougwilson]

What is the goal of the pr? There is no description to understand the goal you are trying to achieve to best guide you.

[Abhishek01039]

Try to use const wherever possible

[dougwilson]

Oh, i see. If that is the case, it seems like a duplicate of #3427

[Abhishek01039]
