Functional programming has eaten software development
Pure functions, immutable data, first-class functions, declarative code
These are all ideas that are now either a best practice in your language, or been adopted outright

The competition provided by Bun and others has led to the recent feature packed node releases
Even if I never actually use Bun in production, I’m thankful for how they’ve pushed the ecosystem forward - VC backed or not

I’m not European and have spent little time in Europe. But my feeling is that culture plays the biggest role
Entrepreneurship and risk taking is less common in the Midwest US because of a more risk adverse culture. I wonder if it’s similar in Europe

I believe the reason it seems difficult is too many beginners are lead straight down the framework path and therefore skip learning the building blocks of JS, CSS, and HTML or even lower level CS concepts

Advice to junior web devs: take time to learn some basic Linux administration skills
Instead of Vercel, Netlify, etc for your next side project, go to Digital Ocean or another VPS provider

UX is downstream of DX
A poor developer experience in language, local environment, CI, testing, deployments, etc will lead to poor products
Therefore, invest in your team’s tooling and processes because any efficiency gained will create a better experience for the end user

Please stop using “I’m an introvert” as an excuse for not practicing pair programming
You don’t like pair programming because of comfort, social anxieties, or a misunderstanding of productivity and collaboration
These are not the same thing as being introverted

Thinking about a stage between junior and senior dev I'm calling the "zealot stage"
This is a phase where devs have enough knowledge to understand the value of new ideas and patterns, but lack the experience to apply them with nuance

My only concern right now would be the surface area of the API. Any app built with Effect would be very sensitive to future breaking changes

All languages have foot-guns and features that can be used in “clever” ways to create unmaintainable code
We should call out those uses specifically instead of blaming the language
Never seen a better ad for ditching TypeScript. You don't have to live like this!!

In React, avoid passing boolean props that determine child component behavior
Instead, pass event handlers that allow the parent component to handle the event accordingly

Learning Clojure's (or similar) functional approach reshapes thinking:
- View code as data streams
- Focus on transforming immutable collections
- Embrace pure functions
Result: Cleaner, more comprehensible code that's easier to reason about. Applicable to almost any language!

You’re reviewing a PR in a TypeScript project and you see a plain for loop instead of forEach, map, reduce, etc.
Do you leave a comment or leave as is?

Feasibility of this would be difficult, but some kind of automatic "merge" capability reminiscent of git would be neat
If the two changes can both be applied without conflict, then take them both, otherwise, deny with the conflict

Skip all the certifications and bloated frameworks and just do this
Honestly. The Agile methods can be boiled down to this:
1. Work in short cycles.
2. Measure what happens.
3. Adapt.
If you don't find story points helpful, don't use story points.
If daily scrums are getting in the way, don't do daily scrums.
If the cycle is too long, shorten

I think it depends largely on architecture and size of the company/team

I’ve found the same. React testing library makes things easier, but it’s really hard to debug without a visual
I rarely use Jest or Vitest for UI testing anymore.
Here's why:
Testing in a real browser using Playwright or Cypress gives me more confidence, more power, and a better DX.
Testing UI components via Jest or Vitest tends to lead to duplicated effort, because I still need to

Doing competitive research by inspecting competitors apps:
Using Bootstrap classes still -> Don't even worry about them
Evidence of redux usage -> Their codebase is probably some over engineered mess

vscode - download and be productive
vim and emacs - requires time and customization to be productive
That sounds like a clear win for vscode, but I think it's a loss because it discourages devs from getting to know their tools on a deep level

A common mistake devs make is expecting unfamiliar tech X to behave like familiar tech Y and then getting frustrated with Y
The true pitfall is when you bend Y to behave more like X instead of taking the time to understand Y and embracing the features that make it powerful
