From b4db31822fd61f2594ab90ce5d38b08b162edddc Mon Sep 17 00:00:00 2001 From: Rich Trott Date: Thu, 28 Jan 2016 20:08:57 -0800 Subject: [PATCH] dgram: scope redeclared variables A few variables in `lib/dgram.js` are redeclared with `var` in a scope where they have already been declared. These instances can be scoped more narrowly with `const`, so that's what this change does.
