The case for Rollup and ES modules in frontend code

TLDR: Rollup and ES modules give us:

smaller bundles due to tree-shaking and scope-hoisting, and
faster runtime perf than CommonJS, by avoiding runtime module resolution

Sources to back up these wild claims:

I ❤️ higher order functions and generally refuse to write non recursive looping structures. With Razor though I didn't have a great way of displaying lists without looping.

###Usage

The following code will render the _link partial for every item in the links list. It is basically a functor from data to output given a template.

@Html.RenderPartials("_link", links)

Without this extension I would have to write something like this

Pony Considerations

If you're thinking of checking out the Pony programming language, here's a list of things that I think are important to know. This list is based on a Tweet that I wrote.

Editor/IDE support

There are Pony packages for several popular editors.

A collection of The Morning Paper posts relating to containers, operating systems etc.

In order of first appearance in The Morning Paper.
