Software reuse is more like an organ transplant than snapping Lego blocks (2011)

This is something that also works well in the nicer parts of javascript. Now nobody is ever going to accuse javascript of being a good functional language (disparage away), but at its core, you've pretty have arrays, maps, numbers, strings, booleans and functions. An Object is really just a map of key-value pairs where some values are functions. You can .map() an array of objects to an array of strings by feeding it a function that turns an object into a string. It's really nice to build those little blocks and cobble them together into something that accomplishes something more complex.

I use to be pretty negative about JS, but typescript saves the day. The lego aspect of functional programming always becomes more evident when you have static types.

I've been getting more mixed about Typescript lately. Quite often, you end up with everything being `any`, and every time you write something, the compiler makes you hunt down the missing types.

But being able to specify interfaces for lambdas is absolutely fantastic. Something like: "this function takes an object and returns a function that can take either a string or a number and returns a number" is easy to do in Typescript, and useful for figuring out where the lego block fits.
