Not forcing super in derived class's constructor?
TLDR: If this is used without super (which should be statically analyzable), let it refer to Object.create(new.target.prototype). Otherwise, let super creates what it refers to. I know the reason to force super in derived class's constructor is to make sure this refers to the exotic object the base class might allocate. But I bet in real world, extending base classes who only create ordinary objec

the Great Tooling Revolution
In the March 24 meeting notes (e.g., rwaldron/tc39-notes/blob/master/es6/2015-03/mar-24.md ), there's the line: DD: once the great tooling revolution arrives, there will be a live GitHub version of the spec that implementers consult. but I don't see any discussion of this in the meeting notes or in es-discuss. Could someone describe the plan? This was discussed briefly at the previous meeting, per

Infrequently Noted
Note: Budgets account for two TLS connections. Many sites initiate more early connections, reducing time available to download resources. Using four connections cuts the three-second budget by 350 KiB, to 1.5 MiB / 935 KiB. The five-second budget loses nearly half a megabyte, dropping to 3.2 / 1.9 MiB. It pays to adopt H/2 or H/3 and consolidate connections. These budgets are extremely generous. E

Another important date is June 18, 2015–it’s when the ECMA General Assembly will vote on and approve the 6th edition of Ecma-262 and usher in the next era of JavaScript. On that day, all those new language features we’ve been coveting/dr
Cancelable promises
As a heads up, there's some debate around the fetch() API how exactly request termination should work and how that affects promises: slightlyoff/ServiceWorker#625 The WebRTC WG has also been discussing canceling in the context of terminating a request for permission from the user. I think they decided to postpone for now until there's a bit more progress on what cancelable promises means, but I wo
