"To take a fine idea and make something great of it... that is what real art is!" - Antonín Dvořák Thought this would be a good kickoff quote to this week's newsletter issue! Come read something, learn something, and practice some coding while you're at it: cassidoo.co/newsletter/

the hard parts of building a business are - solving a real problem for real people - ignoring shiny ideas that are fun but distracting - prioritizing boring stuff that moves the needle - connecting with customers if anything, AI makes it *harder* to build a successful business

On this episode of @codepen.io School, we solved the latest @cassidoo.co Newsletter challenge using the new Jest Block: codepen.io/editor/team/... Naturally @chriscoyier.net and I did it LIVE ON-AIR with Zero Prep and Research but somehow managed to solve it. youtu.be/BFvGpJTAr54?...

Y'all! We've got Jest now. Here's an example of Tenzy's solution written as a *.test.js file. codepen.io/editor/chris... Might be kinda fun to set up the expected answers as tests first, then write the function to satisfy it. hash tag TDD BB

Genuine question: I see a lot of the new code hosting platforms sharing the AI prompts you use to get the final code. Is that actually useful? Pre-AI, I didn't care about the order in which you typed your code, for example, I just look at the output/PR details. It seems like unnecessary context?

I went back to handwritten notes about a month ago for learning. My comprehension, memory retention, and ability to reason about code improved significantly! These days, every time I write a prompt, I always remind myself of @cassidoo.co‘s post. I’m thinking about making flashcards again.

Do not give up your brain

It's tempting to just let tools think for you, but you still need to be able to think for yourself and stay sharp.
