Today, we’re deprecating Create React App for new apps, and encouraging existing apps to migrate to a framework.

We’re also providing docs for when a framework isn’t a good fit for your project, or you prefer to start by building a framework.

As devs, we're often striving for impact that isn't measured in lines of code written.
Aiming to increase profits, improve user experience or simply make the world a better place? One thing is still true:
For our impact to reach beyond tech itself, our skills and efforts need to do so as well. 🚀

¿No entiendes los JOIN en SQL? ¡Eso se acabó!
Guía visual que te los explica con ejemplos de código ↓
INNER JOIN: Muestra la intersección de A y B. Consulta: SELECT * FROM A INNER JOIN B ON A.key = B.key; FULL JOIN: Muestra la unión completa de A y B. Consulta: SELECT * FROM A FULL JOIN B ON A.key = B.key; FULL JOIN con NULL: Muestra los elementos no coincidentes. Consulta: SELECT * FROM A FULL JOIN B ON A.key = B.key WHERE A.key IS NULL OR B.key IS NULL; LEFT JOIN: Muestra todos los elementos de A y los coincidentes de B. Consulta: SELECT * FROM A LEFT JOIN B ON A.key = B.key; LEFT JOIN con NULL en B: Muestra elementos de A sin coincidencia. Consulta: SELECT * FROM A LEFT JOIN B ON A.key = B.key WHERE B.key IS NULL; RIGHT JOIN: Muestra todos los elementos de B y los coincidentes de A. Consulta: SELECT * FROM A RIGHT JOIN B ON A.key = B.key; RIGHT JOIN con NULL en A: Muestra elementos de B sin coincidencia. Consulta: SELECT * FROM A RIGHT JOIN B ON A.key = B.key WHERE A.key IS NULL.

How is this a surprise?

Your best people also have the most options on the market and get the best offers. They are the first to leave.
You're now left with a worse workforce on average. Add a massive drop in morale, engagement and motivation to that, abd the math does itself...

I think it's good to write these “some very specific thing didn't work, here's how I fixed it” blog posts: In case somewhere, someday, someone happens to have the same issue:

The neat thing about the new Motion by @citizenofnowhe.re supporting plain JS is I can use plain @astro.build files, have nice animations and use zero React anywhere.

Meetings to design processes to set up more meetings to improve communication to work more effectively on the 2 hours you have left after all these meetings....

This is why teams that are empowered and trusted to just "take the ball and run" are beating the crap out of big enterprise organisations
