Bug 170151 – String.prototype.replace incorrectly applies "special replacement parameters" when passed a function

• Component: JavaScriptCore
• Status: RESOLVED FIXED

When String.prototype.replace is passed a function as a second parameter it is incorrectly applying "special replacement patterns" to the returned results

var a="ABC";
a.replace("B", function(){ return "$$" });  // Should be "A$$C" - in Safari 10.1 and 10.2 it is "A$C"

Please close out the bugs when landing fixes. Also, no need for r? on any patches once things have landed.

Sorry, but I don't have permissions to do this, I only  can close bugs that I created. Yeah for this bugs I've have been waiting until webkit nightly starts works to ask authors to check fix and close the issue.

Ah, ok. Let me try to get you edit bugs privileges so you can close bugs you didn't create.
