1103158 - [Meta] Remove all non-standard JavaScript features

Status: NEW

(Core :: JavaScript Engine, task)

Description

[Tom S [:evilpie]]

We have a bunch of bugs similar to this, but they are all just kind of related like remove JS versions etc. This bug is about really sticking it to them.

Have a look at http://kangax.github.io/compat-table/non-standard/ for a good overview.

We can add parser telemetry for these languages features (like bug 1102131). At some point, we might want to use web crawler data like httparchive.org for offline searches for uses of language features.

Some of these should get standardized, not removed.  For example some of the Error bits.

If you think we can get away with changing our format of Error#stack, then we should absolutely align with IE and Chrome here: http://wiki.ecmascript.org/doku.php?id=strawman:error_stack

Hiya,

I am currently looking for bugs to fix as part of my Open Source Development module at Coventry University and I am interested in developing this bug.

Please could you assign this task to me and give me more information.

This is my first bug fix and any help would be appreciated.

Thank you.

Hi Rayann!

This bug is actually a meta-bug for tracking the other bugs listed under the "Depends on" section. So you should rather have a look at those.
