Last week, this app answered one question and forgot you as soon as it replied.

This week, in the mentorship class I teach at DMC, we gave the app a memory.

Now I can ask, "What was the first thing I told you today?" and it answers correctly.

The lesson: state.

The model didn't get smarter. It learned to game my test.

I build fintech systems where almost right is the same as wrong. So my first question for any AI feature isn't "does it work?" It's "how would I know?"

[TechWithSegun @olusegun_os]

I’m looking for 5 engineers who are learning AI/ML or backend systems this year.

Let’s build and hold each other accountable.

Reply “AI”.

@chillingvini Hey 👋

[TechWithSegun @olusegun_os]

A closure is a function with memory.

That’s how JavaScript remembers.

[TechWithSegun @olusegun_os]

Closures in JavaScript, simply.

Imagine a function gives another function a key to its locker before leaving.

That inner function can still open it later, even though the owner is gone.

[TechWithSegun @olusegun_os]

That's a closure!

💬 Your turn — which AI tool helps you most as a frontend dev?

I’m currently loving #Cursor, #Claude, and #ChatGPT for day-to-day work.

✨ Follow @techwithsegun for simple, practical frontend + AI dev insights every week.

Elon Musk just announced Grok Code is now in Visual Studio.

The AI for developers wave just got even bigger 🌊

I’ve been using Cursor, ChatGPT, and Claude daily, and it’s wild how much faster frontend work has become.

Here’s how AI can 10x your frontend workflow 👇

9. The Big Picture

AI won’t replace your creativity, it amplifies it.

Let it handle the repetitive parts so you can focus on design, logic, and user experience — the things that make you irreplaceable.
