Instead of prohibiting ‘return undefined’ (#8669), we require that a
function must return an explicit value always or never. This prevents
you from forgetting to return a value in some cases. It will also be
important for TypeScript, which distinguishes between undefined and
void.

ES and TypeScript modules are strict by default and don’t need this
directive. ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.

Prettier would do this anyway, but it’s separated out for a more
reviewable diff. Generated by ESLint.

This cleans up the handoff of page_params
data between ui_init and modules that
take over ownership of page_params-derived
data.
Read the long comment in ui_init for a bit
more context.
Most of this diff is actually test cleanup.
And a lot of the diff to "real" code is
just glorified `s/page_params/params/`
in the `initialize` functions.
One little oddity is that we don't actually
surrender ownership of `page_params.user_id`
to `people.js`. We could plausibly sweep
the rest of the codebase to just use
`people.my_user_id()` consistently, but it's
not a super high priority thing to fix,
since the value never changes.
The stream_data situation is a bit messy,
since we consume `page_params` data in the
initialize() function in addition to the
`params` data we "own". I added a comment
there and intend to follow up. I tried
to mostly avoid the "word soup" by extracting
three locals at the top.
Finally, I don't touch `alert_words` yet,
despite it also doing the delete-page-params-data
dance. The problem is that `alert_words`
doesn't have a proper `initialize()`. We
should clean that up and have it use a
`Map` internally, too.
Babel strict generates more code for [...x] than you’d like, while
Babel loose mode assumes x is an array.

We have ~5 years of proof that we'll probably never
extend Dict with more options.
Breaking the classes into makes both a little faster
(no options to check), and we remove some options
in FoldDict that are never used (from/from_array).
A possible next step is to fine-tune the Dict to use
Map internally.
Note that the TypeScript types for FoldDict are now
more specific (requiring string keys). Of course,
this isn't really enforced until we convert other
modules to TS.
This commit was originally automatically generated using `tools/lint
--only=eslint --fix`. It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.

AFAIK I should this never fail, hence the blueslip.error line. But it
is failing in practice when rendering user groups after looking them
up by ID, and the error handling should definitely be softer.
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
We do not update user_group_name_dict when name or description is edited,
which may lead to errors if get_user_group_from_name is called, so to fix
that we update user_group_name_dict also.
The edited group iswas going to the bottom, it is not staying at its
position, so to fix this we sort by ids of the groups to maintain
proper relative order.
(Original commit also fixed another issue, but Tim replaced that with
the previous commit for a better solution).
Fixes#8692.
This fixes the user groups UI to follow the Zulip standard mechanisms
(using the appropriate server_events system to update all browsers
properly). It also, as a side effect, fixes#8692, since it
eliminates the weird behavior of trying to re-insert a user group
after reformatting it in the frontend.
Thanks to Tarun Kumar for preliminary work on this.
Also adds a custom rule to eslint. Since the recommended way of extending
eslint is to create plugins as standalone npm packages, the separate rule
is published as 'eslint-plugins-empty-returns'.
Fixes#8669.
This fixes the real-time sync for the user groups membership data
structure to work like these work in the rest of Zulip; now, edits
made in one browser are immediately and correctly reflected in other
browsers.
Using user_group_name_dict.get() will return `undefined`.
`blueslip.error` statement caused an exception notification to the
admins.
Tweaked by tabbott to add a test for a nonexistent group.
