Incompatibilities between ES3 and Proposed ES4

# Lars Hansen (18 years ago)

We've put up a document on ecmascript.org that details all known incompatibilities between ES3 and Proposed ES4: www.ecmascript.org/es4/spec/incompatibilities.pdf.

Dave summed it up nicely, I think:

"It's also interesting to think of conservative extension not as an all-or-nothing property, but to judge incompatibilities in terms of their impact. This document attempts to enumerate and classify the different ways the proposed ES4 spec conflicts with the specification of ES3." lambda-the-ultimate.org/node/2524
