Honestly, it makes a ton of sense for Microsoft to buy GitHub. After this acquisition, they will control:

The word is "compile", not "transpile".
They mean the same thing. JS developers invented a new word because they weren't used to working with compilers before Babel came out. But "Babel is a JavaScript compiler". So is tsc. That's what the "c" stands for; compiler.
Ofc, it…

So, React recommends:
- you should use a framework with React
- frameworks should pin to a canary version of React in order to take advantage of the latest “stable” features that do not yet appear in a stable release

Microservices are an indication of organizational issues. They are an escape hatch for engineers who don't have the power they need to do their job correctly, so they try to break off a tiny silo. Over time, you incur tremendous overhead from all the fragmentation.

True, the food is great.
The fact that you don’t realize that there are up to 1200 “microservices” being called when someone uses the Twitter app is not great.

• Route ranking 📊
• Relative routing and links ⛓
• Completely rewritten with React hooks 🎣

Counterpoint: Java (Scala) microservices we’re an absolute nightmare for us at Twitter as we migrated off Ruby on Rails. Much of the complexity that Elon mentioned after he bought the company was from this architecture.
At

The difference between `null` and `undefined` in JavaScript:

HOCs are like decorators. You wrap a component with some state/behavior to make a new one.
Render props are like delegates. You specify a function that gets called once you have your state ready to go, and delegate the rendering.
