TypeScript supports Pick to allow you to get a "subset" object type of a given type, but there is no built-in Pick for deeper nested fields.

If you have a function that takes a large object as argument, but you don't use all of its fields, you can use Pick, Pick2, Pick3, etc to narrow down the input type to be only just what you need. This will make it easier to test your function, because when mocking the input object, you don't need to pass all fields of the "large" object.

The Joy of Composition

Why stateless rendering is pure bliss

React just got stateless components, meaning that they are in essence pure functions for rendering. Pure functions make it dead simple - even fun - to refactor your views

ES6 Defaults / Overrides Pattern

Combine default parameters and destructuring for a compact version of the defaults / overrides pattern.

    bar = 'no',
    baz = 'works!'
  } = {}) {
