'use strict' is required for my setup

[GJSmith3rd]

It seems I have to use

'strict mode';

DEBUG CONSOLE

node --debug-brk=15576 index.js
Debugger listening on port 15576
/home/gjsmith3rd/Workspaces/GIT-Projects/dns-over-http2/index.js:28
let question = req.question[0], hostname = question.name;

If I add 'strict mode' the code now runs but I'm confused about the parameters in dns-over-http2.json.

yes i have added To My too As i saw it recently in your 528cffd but forgot it in the pull request..

well if first line strict or Not i don't get this errors?and can't see difference with Node v6.8.0 Debugger listening on [::]:15576
for parameters @yyfrankyy would be better To ask about https://github.com/yyfrankyy/dns-over-http2

Maybe because I'm on Node v4.2.6 - I'll look into upgrading.

node --v8-Options
shows me:
--use_strict (enforce strict mode)
type: bool default: false
