Polls (compatibility requirements)

[David Majda]

Hi,

I'm working on determining compatibility requirements of future PEG.js versions. To help with that, I created two polls on Twitter with these questions:

• What is the lowest Node.js version you use PEG.js with?
  
• If your PEG.js parsers need to work in Internet Explorer, what is the lowest version you need to be supported?
  

If you are a PEG.js user, I'd be happy if you could spend few seconds to answer them. It will help me a lot. Thanks!

I'm working on determining compatibility requirements of future PEG.js versions. To help with that, I created two polls on Twitter with these questions:

• What is the lowest Node.js version you use PEG.js with?
  
• If your PEG.js parsers need to work in Internet Explorer, what is the lowest version you need to be supported?

Thanks everyone who participated in the polls! The most important results are:

• Only 20% users use PEG.js with Node.js 0.10.x or 0.12.x.
• Only 9% of users creating parsers that need to work in IE need IE8 to be supported.

This mostly confirmed what I thought. As a result, I'll go ahead with two changes:

• Dropping IE8 support. This will allow to drop various utility functions and remove some cruft from the codebase. Note that IE8 is not supported by many other JavaScript projects these days (e.g. React, jQuery, Chai). 
• Dropping Node.js 0.10.x & 0.12.x support. This will allow to use some ES6 features such as classes or let & const. While 20% of users still use PEG.js with 0.10.x or 0.12.x according to the poll, I expect the number to drop significantly before the next release -- partly because maintenance of these versions ends in Oct/Dec 2016. 

The changes are tracked by #441 and #442 and I plan to implement them in the next few days.
