𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 𝐏𝐥𝐚𝐜𝐞𝐦𝐞𝐧𝐭 𝐢𝐧 𝐇𝐓𝐌𝐋 1. The <​script> Tag - JavaScript code is embedded in HTML using <​script> and <​/script> tags. - Old examples may use type="text/javascript" which is now optional since JavaScript is the default scripting language in HTML. 2. JavaScript Functions and Events - Functions are blocks of JavaScript code executed when called, often triggered by events like user actions (e.g., clicking a button). 3. JavaScript Placement - Scripts can be placed in the <head>, <body>, or both sections of an HTML document. Learn JS from W3Schools.com Want more JavaScript insights?

🧐 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝 .𝐍𝐄𝐓 𝐄𝐜𝐨𝐬𝐲𝐬𝐭𝐞𝐦 𝐁𝐞𝐟𝐨𝐫𝐞 𝐘𝐨𝐮 𝐃𝐢𝐯𝐞 𝐈𝐧𝐭𝐨 𝐈𝐭! Knowing what drives .NET application is important for you to build right .NET applications targeting the requirement. What are .NET Framework, .NET Core and .NET Standard? .𝐍𝐄𝐓 𝐅𝐫𝐚𝐦𝐞𝐰𝐨𝐫𝐤 -> The original implementation of .NET, introduced by Microsoft in 2002. -> Primarily used for building Windows-based applications, including desktop and web applications. -> Supports Windows-specific APIs, provides a rich set of libraries and includes the Common Language Runtime (CLR) for managing code execution. -> For windows based user interface, Win-Forms (outdated) and WPF can be used. .𝐍𝐄𝐓 𝐂𝐨𝐫𝐞 -> An open-source, cross-platform implementation of .NET. -> Suitable for building applications that run on Windows, Linux and macOS. -> High performance, scalability, support for micro-services and command-line tools for all supported platforms. -> For cross platform user interface, MAUI can be used. .𝐍𝐄𝐓 𝐒𝐭𝐚𝐧𝐝𝐚𝐫𝐝 -> Not an implementation but a specification that defines a set of APIs that all .NET platforms must implement. -> Ensures compatibility across different .NET implementations (Framework and Core), making it easier to share code between them. -> Provides a common set of APIs for .NET Framework, .NET Core and Xamarin. 𝐁𝐨𝐧𝐮𝐬 -> Before .NET Core, Mono was the .NET implementation for cross platform support. -> Unity Game Development was integrated with this Mono framework to target cross platform application with single source code implementation. -> All the older .NET application are slowly migrating to .NET Core for better performance overall and to be in current trend pool with latest features. -> If you are looking to build a .NET library yourself to support both .NET Framework and .NET Core, your go to target framework is .NET Standard. -> .NET Framework support is promised for lifetime by Microsoft. -> .NET (core) 8.0 is the long term support version, which will end by 2026. _______________________________________ Stay Curious! 🖥️ ✨ Keep Learning...

من أجل التحقق وحماية الملفات المرفوعة، وخصوصاً صيغ الملفات يوصى عن طريق التابع ()extension على التابع ()getClientOriginalExtension طيب ليش؟؟ التابع ()extension بخمن الصيغة المناسبة للملف المرفوع وهو المستخدم في النسخ الجديدة من Laravel أما التابع()getClientOriginalExtension برجع الصيغة الأصلية يعني إذا رفعت ملف اسمو car.png (المستخدم عدل الصيغة يدوياً) وصيغتو الأصلية car.pdf بالتالي هو وثيقة إلكترونية مو صورة  ()extension عند استخدام التابع png برجع pdf بدو يرجع ()getClientOriginalExtension والتابع ()extension أي لحماية أفضل واجراءات وقائية أقوى يوصى بال ملاحظة: ما تخزن اسماء الملفات متل ما هية واردة من المستخدم بل توليد اسم مميز عشوائي لكل ملف For those who are passionate about web development and security, understanding the nuances between file extensions and MIME types is crucial. It's not just about knowing .png from .pdf; it's about ensuring the integrity and safety of the files we handle every day. 🛡️ In Laravel, a popular PHP framework, developers often encounter scenarios where they need to validate and manage uploaded files. Two methods stand out in this context: extension() and getClientOriginalExtension(). 📁 extension(): This method guesses the file's extension based on its content. It's like having a magic lens that looks at the file and says, "Ah, this is a PNG!" It's incredibly useful because it doesn't rely on what the client tells us; it figures it out itself. 💪 getClientOriginalExtension(): On the other hand, this method returns the original extension provided by the client. So, if you upload a file named car.pdf but it's actually a picture (with the content of a PDF), this method would report it as a PDF. It's like asking the uploader, "What do you say this is?" and they tell you. 🤷‍♂️ Understanding the difference is key. If you're uploading a document that's mistakenly named with a .png extension but contains PDF data, extension() will correctly identify it as a PNG, while getClientOriginalExtension() will misleadingly report it as a PDF. This distinction is vital for preventing malicious files from slipping through our defenses. 🔒 So, next time you're handling file uploads in Laravel, remember: trust the content over the name. Use extension() for a secure guess based on the file's true nature, and getClientOriginalExtension() for when you need to know exactly what the uploader thought it was. Together, we keep our applications safe and secure #Laravel #PHP #Security
