Yesterday, I decided to post a bounty on a feature request to add support for ES6 parameter default values. I put $50 and a few minutes later the bounty was increased to $150. Then I sent out this tweet and went to grab some food:
if you want $150 for a couple of hours of open source hacking, add support for default params to @jshint: https://t.co/ZnJG7G2a1X— Anton (@valueof) July 30, 2013
One hour later an incredible Thomas Boyt posted his solution which I reviewed, landed and published today as JSHint 2.1.8. This means that JSHint now officially supports default parameters!
