What I’d Teach a Junior Dev in Their First 30 Days

Starting out as a junior developer can feel like stepping into a jungle with no map.

You’ve got tutorials everywhere, frameworks screaming for attention, and advice coming from every direction (including that one guy on YouTube who insists you’re doomed if you don’t learn data structures first).

So if I had to mentor a junior developer for 30 days — just one month — I’d ignore the noise and focus on what actually matters.

Not fluff. Not buzzwords. Just what will make you dangerous in the real world.

Let’s go 👇

Week 1: Understand How the Web Works

Before you even think of a framework, you need to understand what happens when someone visits a website.

Here’s what I’d teach:

• What is a client vs a server?
• What happens during an HTTP request?
• What is an API, and how does the browser fetch data?
• What are HTML, CSS, and JS actually doing?

Most devs jump into code before they know why the code exists.
That’s like trying to cook a dish without knowing what it’s supposed to taste like.
