Description

Internet Explorer 8 does not support Object.keys.

Fomafix raised the priority of this task from to Needs Triage.

Fomafix updated the task description. (Show Details)

Fomafix added a project: JavaScript.

Fomafix subscribed.

@Fomafix: Which software project is this about? ULS? MediaWiki core? Adding one is welcome.

MediaWiki core has the es5-shim module, which provides this method (among others). ULS should presumably just add a dependency on it.

es5-ship in core is the right position.

But es5-ship currently does not create Object.keys. This has to be implemented.

Then ULS can depend on es5-ship.

It most definitely does create Object.keys, the code is in /resources/lib/es5-shim/es5-shim.js starting on line 752 onward.

I read the wrong file. es5-shim already creates Object.keys.
