    AI agents are not science fiction anymore. They’re here, and they need human partners who know how to build and guide them. If you want to work with agents, don’t start with fancy models. Start with the fundamentals. - Learn Python. Most agent frameworks are built in Python. LangChain, LangGraph and CrewAI all use it as their foundation, and even enterprise tools like Semantic Kernel support Python alongside C# and Java. Python is how you customise behaviour, manage memory and connect to data. - Learn JSON. Agents call functions and tools by outputting a JSON object with the function name and parameters. The model doesn’t run the call. Your code does. If you can’t parse and construct JSON, your agent stays mute. - Learn SQL and vector search. Agents need long‑term memory. They use SQL to retrieve structured data and vector databases to recall information in Retrieval Augmented Generation. Understanding how to query both will let you feed your agent accurate context. - Learn YAML or config scripting. Frameworks like CrewAI define agents, roles and workflows in YAML or Python files. Editing these files is how you choreograph multiple agents. - Learn APIs and schemas. Every tool the agent uses, from weather data to code execution is defined by a schema. Knowing how to design and call APIs turns a language model into an actor. These skills aren’t glamorous, but they’re the backbone of agentic AI. Get to know them and you’ll be ready for the future of work. What will you learn next?

  • Web development, software development, and machine learning – each path in coding brings unique challenges and rewards. 🚀 From building dynamic websites with HTML, CSS, and JavaScript, to building powerful applications with Java, C++, and Kotlin, or exploring data and AI with Python, R, and SAS, the tools we use shape the world we create. 🛠 No matter the language, keep coding, keep learning, and keep innovating. The future is built on your code! 💻 #WebDevelopment #SoftwareDevelopment #MachineLearning #Coding #Tech #Developers

  • Ever catch yourself wondering if you should learn another language that’s only been around a couple of years? “Rust is hot.” “Kotlin is trendy.” “Python is everything.” And then you hesitate to pick up Java because you’ve heard it’s “old” or “over." Here’s the thing: - Java runs on 7 billion devices - Powers 90 % of Fortune 500 back‑ends. - Nine million developers use it every day. It’s the language behind your bank app, your Android phone, most big‑data frameworks and millions of embedded devices. It’s not sexy hype. It’s a robust ecosystem of libraries, frameworks and communities that will still be here in ten years. Java’s mantra is “Write once, run anywhere.” Compile it once and it runs on Windows, macOS, Linux, the cloud, Raspberry Pis and even Mars rovers. Its strong typing and object‑orientation force you to learn real computer‑science fundamentals, and once you’ve mastered Java, learning Python or JavaScript becomes simple. New features like records, pattern matching and virtual threads keep Java fresh. Long‑term support releases mean your skills will stay relevant for the next decade. And because the language is everywhere, Java developers command salaries that more than double the median U.S. wage. The lesson? Invest in mechanisms that last, not just trends. Good fundamentals outperform good fads. #programming #java #w3schools

    👨💻 Just kicked off my Python journey on W3Schools! It’s my first step toward becoming an AI/ML Engineer — excited (and a little nervous 😅), but ready to learn one line of code at a time. 📈 11% done already — small steps today, big goals ahead! If you’re also learning Python, AI, or ML — let’s connect and grow together! #Python #AI #MachineLearning #LearningInPublic #CodingJourney #AIMLEngineer #W3Schools #FutureEngineer #KeepLearning

    A few days ago, I found out that W3Schools.com had a great discount on their courses and exams, so I purchased it (and I think the offer is still available now). I had already taken the exams for HTML, CSS, and Bootstrap and received their certificates. But then I noticed they’ve added a new type of exam for each course, where the questions get updated and become more challenging based on your answers. It felt much more engaging and challenging, so last night I decided to take the HTML exam again without going through the course — just to see how I’d do. The questions were truly excellent and kept getting harder. The result? I scored 97% correct answers. It really motivated me to go ahead and take the exams for all the front-end courses, plus MySQL and PHP. I’ll be sharing those certificates here as well once I complete them! I’m happy to share that I’ve obtained a new certification: HTML5 Application Development Fundamentals from W3Schools.com! ‎چند روز پیش متوجه شدم که w3school یه آف عالی روی دوره هاش و ازمون هاش گذاشته و خریدمش (الان هم فکر کنم اون آف رو گذاشته) ‎من ازمون دوره های html و css و bootstrap رو داده بودم و سرتیفیکتشون رو هم گرفته بودم، اما متوجه شدم یه نوع آزمون دیگه اضافه کرده به هر دوره که خود ازمون بر اساس جواب هایی که میدی سوالات بعدی اپدیت میشن و سخت تر میشن، احساس کردم خیلی چالشی و بهتر میشه پس دیشب تصمیم گرفتم بدون دوره کردن html ازمونش رو بدم و ببینم نتیجه چی میشه، سوالات واقعا عالی بودن و چالشی تر میشدن و این شد نتیجه کار با ۹۷٪ جواب درست، بهم انگیزه داد تا ازمون همه دوره های front-end و mysql و php رو هم بدم و سرتیفیکت ها رو اینجا مجددا share کنم.

    This needs to be said. We talk about AI and frameworks, but most people still can’t read the language that holds everything together. HTML isn’t advanced code. It’s just a handful of tags that tell a browser what’s a heading, a paragraph or a picture. Learn it once and the web opens up. Everything you see online sits on HTML. Learning it makes every other language easier. People who know HTML such as marketers, copywriters, product managers, move faster and make smarter decisions. It’s digital literacy that gets you into the conversation. Build your own portfolio or landing page and you save money and avoid frustration. Templates are good. Independence is better. Employers still look for people who understand the basics. Judgment matters more than automation. That’s why I recorded a short video on why HTML still matters. It’s a call to raise the bar for yourself and your team. Don’t just consume the web. Shape it. Are you ready to go from scrolling to creating?

  • ☕ AI can whip up code faster than you can brew coffee, but it’s often like a smoothie with random ingredients. MIT researchers point out that AI‑generated code can look legit while calling functions that don’t exist or breaking your internal conventions. And because machines don’t understand your business goals, only humans can ensure code aligns with the bigger picture. So, before you blindly copy and paste, learn the fundamentals. It’s the human insight, reading, refactoring and testing code, that makes AI a co‑pilot, not your autopilot. W3Schools is here to help you build that foundation. Ever had to untangle AI spaghetti code? Drop your war stories below. ⚔️

  • We've all been there, scratching our heads over variable names like 'x' or 'y', functions that seem to go on forever, and comments that add more confusion than clarity. Writing clean code is essential to avoid such scenarios and ensure a smooth development process. It makes your code self-explanatory, easy to navigate, and maintainable, saving you from future headaches.💪 Adopting clean code principles improves code readability, makes debugging easier, reduces the cost of program maintenance, better collaboration, improves code quality, and makes you a better programmer.💻 Write and practice your code with W3Schools Spaces.
