Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

# This is not a true debounce in that it will not prevent \code{expr} from being
# called many times (in fact it may be called more times than usual), but
# rather, the reactive invalidation signal that is produced by expr is debounced
# instead. This means that this function should be used when \code{expr} is
# cheap but the things it will trigger (outputs and reactives that use
# \code{expr}) are expensive.

nest.js

A multi-level groupBy for arrays inspired by D3's nest operator.

Nesting allows elements in an array to be grouped into a hierarchical tree structure; think of it like the GROUP BY operator in SQL, except you can have multiple levels of grouping, and the resulting output is a tree rather than a flat table. The levels in the tree are specified by key functions.

See this fiddle for live demo.
