Just got a mobile app dev job from TikTok. A brand reached out after seeing my content. Visibility works. #TechTwitter #BuildInPublic #Developers #Freelance #Programming

In 2026 you don’t need anything other than react native to build fast and good looking mobile apps.

Every modern app depends on functions that run at the right time. Some functions run immediately. A user taps a button. The system calls loginUser(). A user submits a form. The system calls createAccount(). A customer taps pay. The system calls processPayment(). These are direct actions. Then there is another category. Functions that are passed somewhere else and executed later. These are callback functions. They become useful when the system must wait for something. A button waits for a tap. A payment gateway waits to confirm a charge. A delivery service waits to update status. A server waits for data from a database. Instead of freezing the system, you provide a function to run when the event finishes. Example: button.onClick(() => openCheckout()) The user may tap now or later. When the tap happens, the function runs. Another example: fetchUserProfile(id, (data) => renderProfile(data)) The system fetches data in the background. When data arrives, the callback runs. This pattern is common in frontend apps, APIs, bots, notifications, and integrations. When to use a normal function: Use it when work should happen now in sequence. Validate form. Calculate total. Generate invoice. When to use a callback function: Use it when work depends on an event, response, timer, or future completion. User click. Webhook received. File upload finished. SMS delivered. Payment confirmed. In system design terms, callbacks help software react to the world without blocking everything else. That is why apps feel responsive while many things are happening underneath.

@swapnakpanda This is a clean roadmap. I like that it’s focused on fundamentals over tools. Only thing I’d add: start building alongside this. Even a simple CRUD app will tie Git, APIs, auth, and integrations together way faster than just learning them in isolation, just an opinion

@EliteDevElijah 1. Start from Git 2. Learn one programming language 3. Learn one framework/library for that language 4. Learn one API style (REST/GraphQL) 5. Learn Authentication & Authorization 6. Learn Integrations (Payment, Caching, MQs, Microservices, Containerization)

Nigerian creatives are built different to be honest. No stable light, no stable internet and we’re still out here delivering quality work on time. Shoutout to us fr 🫡

we now live in an era where custom coding is faster than drag and drop.

If you’re a developer and your portfolio is just a Canva page… you’re already limiting yourself. Your portfolio should be something you built. It should show: • Your stack • Your GitHub (active, not empty) • Real projects Because recruiters are not just looking at design… they’re looking at what you can actually do. The moment you build your own portfolio, you stand out immediately. #TechTwitter #Developers #Programming #BuildInPublic #CareerGrowth

Later we go talk about those developers wey still dey use Canva page for their portfolio 💼

Skill alone won’t carry you. If no one sees your work, it doesn’t matter how good you are. Visibility matters. #TechTwitter #Developers #Programming #BuildInPublic #CareerGrowth

We are in the information age. This is a generation where you need to be able to express yourself. You must be able to speak clearly and convey your information with confidence, as an inability to do this will limit you. #Communication #SoftSkills #GrowthMindset #Leadership #InformationAge

People really be PISSED when you turn out smarter than they expected.

The real reason you’re not confident in coding… is because you’ve never built anything alone.

This kind of husband 🤣😅

The humble walk of a dev who knows when to say NO. 😆

Authentication ≠ Authorization Verifying a user is not the same as giving access. Login = identity Permissions = access Mixing both =security issues. #TechTwitter #Backend #Security #Programming #DevTips

Fetch method vs Axios in React.js. When deciding between Fetch and Axios in React, the choice usually depends on the complexity of your project. Fetch is the built-in browser API—great for simple GET requests with zero setup. Axios is a third-party library that requires installation but adds powerful features that save time on larger projects. Here is the technical breakdown of how they differ: 🤖 Automatic JSON Parsing · Fetch: Manual. You must call response.json() to get the data, which adds an extra step. · Axios: Automatic. The response is immediately available under response.data, keeping your code concise. 🚨 Error Handling · Fetch: Only rejects on network failures. It treats HTTP errors (like 404) as successful responses, so you must manually check response.ok. · Axios: Rejects the promise on any status code outside the 2xx range, allowing you to catch all errors in one block. ⚙️ Key Features · Fetch: Lacks built-in request/response interceptors. · Axios: Includes interceptors (great for auth tokens), request cancellation, and upload/download progress tracking. 📦 Syntax & Setup · Fetch: Native to modern browsers—no installation required. · Axios: Requires installation (npm install axios) and import statements. 🔧 Code Comparison Here is how a typical GET request looks side-by-side: Fetch (Native) ```javascript useEffect(() => { fetch('api.example.com/data') .then(res => { if (!res.ok) throw new Error('Network error'); return res.json(); }) .then(data => setData(data)) .catch(err => console.error(err)); }, []); ``` Axios (Library) ```javascript useEffect(() => { axios.get('api.example.com/data') .then(res => setData(res.data)) .catch(err => console.error(err)); }, []); ``` 💡 Which One Should You Use? Both tools get the job done. The best choice depends on your specific needs: · Use Fetch if you are building a small app, want to avoid extra dependencies, or are targeting only modern browsers. · Use Axios if you need broader browser support (including older versions), want cleaner syntax with automatic JSON parsing, or require advanced features like interceptors or request cancellation. In short, Axios handles the boilerplate for you, while Fetch gives you a lightweight, no-setup solution. #webdevelopment #webdeveloper #react #javascript #frontend
