Migrating from deprecated AngularJS

[profesyonal]

AngularJS is no longer supported, which means its continued use could pose a security risk to the site.

Google recommends migrating to Angular, but I don't know enough to know whether this is the best thing to switch to.

We previously discussed switching from AngularJS in the comments on a pull request, because AngularJS is dog slow at rendering anything with lots of components. (Or we're simply using it wrong.)

A good test to evaluate whether another framework is worth switching to would be to replicate the component for showing a single sentence with its translations, and then measure the performance when the number of translations is in the hundreds.
