For example, it wasn't until Typescript 2.0 that we got null checks!

- https://www.typescriptlang.org/docs/handbook/release-notes/t...

  function getLength(s: string): number {
    return s.length; //  Runtime crash if s is null/undefined
  }
  
  getLength(null); // TypeScript <2.0 would not error here

Please give examples of this.

  Not all of its parts are U.S. made: Other components come from China and other Asian countries. [...]
  The screen and battery come from China and the rear-facing camera comes from South Korea.

  Tariffs likely won’t affect his costs at his current production rates
  because he ordered a large batch of parts when he started and still has
  them in supply at his facility. Weaver says that a long-term tariff on
  imported electronics could make the Liberty Phone’s manufacturing cost
  more competitive, since the cheap components would only see marginal
  increases, and more components are likely to be built in the U.S. soon.

Also "more components are likely to be built in the U.S. soon" - says who? How much is "likely," and how soon is "soon?" Lazy reporting at the end with practically no push back from the WSJ writer.

For 10 years, actually. ES6 - otherwise known as ECMAScript 2015 - did in fact come out 10 years ago.

It truly did improve the JS landscape by an order of magnitude.

For those unfamiliar with the extensive features this brought to JS, here is a good list:

  Ship First, Refine Never
  
  Write good enough code that solves a user’s problem and only optimise when metrics demand it.

  Too often, we’re focused on perfectionism or premature optimisation, which prevents getting our code in the hands of users quickly.
  
  - Identify the critical components of your feature.
  - Deliver only those to the user.
  - Users just want to click the button, do the thing, and move on—anything else is wasting time.

Namely, talk to your customers, or use software to see how they are using your product. Often times, we don’t get something right the first time, so the idea that you’d aggressively deprioritizing refinement seems like a mistake.
