Some older packages are now included in the ECMAScript standards

[maxsynnott]

Some package's purposes are now solved by the standard javascript libraries and supported by all modern browsers.

Examples include:
just-entries (replaced by Object.entries)
just-values (replaced by Object.values)
just-left-pad (replaced by String.prototype.padStart)
just-right-pad (replaced by String.prototype.padEnd)
etc..

I think we should remove these packages from the code base and potentially add a deprecated warning to encourage existing users to switch to the standard versions.

The philosophy of just is all about avoiding unnecessary code and reducing bloat. I think some of the packages in this repo unfortunately might currently be contributing to unnecessary bloat and so we shouldn't encourage their further use.

Thoughts @angus-c ?

If agreed I will compile a list of packages I think should be deprecated and we can discuss them here.

Hey Max,

Yeah this is a difficult one. Theoretically Just still supports Node 6 which does not ship any of these utilities natively. But yeah in practice the value seems low.

Perhaps the README (and the REPL) could include a link to nudge people towards the native version.

Ok @maxsynnott, since just-clone needs to support Map and Set input I've used ES5+ syntax there—so I've updated the platform support https://github.com/angus-c/just#browserplatform-support-computer

Upshot is, yes, I think it's now time to deprecate some packages. Maybe we could start by just adding a "deprecated—use ..." label at the top of the associated READMEs. This could probably be abstracted via https://github.com/angus-c/just/blob/master/md-variables.json

Perhaps the docs for each of these could call out the ES6+ alternative with a note of when it became available?
