The `append` method can handle arrays, so there's no need to loop
through each element.
There's more to improve on this method, like the `asc` variable being
global to a table instead of depending on the current column, but for
now I'm only refactoring and maintaining the current behaviour.
These methods were added in 2009 and are supported by 98.5% of the
browsers, including Internet Explorer 9, 10 and 11. We were already
using them in some places.
Calling it directly might make it difficult to detect bugs, particularly
when we don't trust the data we receive:
https://eslint.org/docs/rules/no-prototype-builtins
If we trust the data we receive, then IMHO we shouldn't even check for
`hasOwnProperty`, since we know what we're going to receive.
In JavaScript, when there isn't a `break` or `return` statement inside a
`switch` case, the next case will be executed as well.
That wasn't a problem here because CoffeeScript automatically inserts a
`return` statement in this specific situation. However, since we don't
want to return the result of the `hide()` operation, it might be easy to
accidentally remove the `return` statement, causing the code to break.
I've added a test for the scenario where neither `break` nor `return`
statements are present, so we don't run into this error.
This code requires the variable `_paq` to be set somewhere, but we never
set it.
In the past Decide Madrid added some custom JavaScript using this code.
However, in CONSUL we're using Ahoy to track events, and we don't have
any documentation about adding custom JavaScript to use piwik nor we've
got any other piwik integration.
The `removeCookie` function is never called, and the `initialize`
function doesn't do anything. The only functions we use here are
`getCookie` and `saveCookie`.
The `initialize` functions don't need to return anything, since their
returned value is never used.
Returning false is a common practice in jQuery to stop an event, but in
plain JavaScript methods it doesn't have any side effects.
Internet Explorer 9 was released eight years ago. Besides that, we don't
really support IE8 anyway, since we show a popup to IE8 users saying
we don't support it, we haven't maintained the IE8-specific CSS file for
years, and we don't test our JavaScript against IE8.
The code `where(id: ids)` is equivalent to `where(id: ids.uniq)`.
Since Rails 5 uses `distinct` instead of `uniq` and in most cases where
we use `uniq` with `pluck` we should simply remove the `uniq` call (as
done in this commit), we're also removing the `Rails/UniqBeforePluck`
rubocop rule.
For performance purposes, we need to find bottlenecks in our
application. Optimizing the performance of small methods doesn't make
the application faster.
I've kept a few cops because applying these ones IMHO make the code
easier to read.
These are rules we were already applying.
We've excluded the `factories` folder for some rules because there's a
factory defining a `context` attribute, which rubocop thought was the
`context` RSpec keyword.
We use staging and preproduction environments, which are not valid by
default.
This rule is useful because misspelling the name of an environment might
otherwise go unnoticed.
