My favourite thing

Learning JavaScript doesn’t have to be intimidating. If you’re just starting out, Here’s how to simplify your approach: Avoid: 🚫 Trying to learn every framework (React, Angular, Vue) before mastering plain JS. 🚫 Jumping into async, closures, or OOP too early. 🚫 Watching endless tutorials without building anything. 🚫 Thinking JavaScript is only for the browser. Instead: ✅ Focus on the core concepts: variables, functions, loops, arrays, objects. ✅ Build small projects like a calculator, to-do list, or quiz app using only JavaScript. ✅ Learn DOM manipulation—how JS connects with HTML/CSS. ✅ Understand event handling and how user interactions work. ✅ Practice debugging with DevTools and log your learning through projects.

Software development is complex, and the fancy names don't help. Hashing vs. Encryption vs. Encoding 𝗛𝗮𝘀𝗵𝗶𝗻𝗴 This is a one-way process used for data integrity verification. When you hash data, you get a unique string representing the original data. It's a one-way street; once you hash something, you can't get the original data back from the hash. While multiple values can theoretically yield the same hash, well-crafted cryptographic hash functions make such collisions incredibly rare and nearly impossible to compute. This property makes it perfect for verifying if someone altered the data. If even one-bit changes in the original data, the hash changes dramatically. 𝗘𝗻𝗰𝗿𝘆𝗽𝘁𝗶𝗼𝗻 This is the real deal when it comes to data security. It uses algorithms and keys to transform readable data (plaintext) into an unreadable format (ciphertext). Only those with the correct key can unlock (decrypt) the data and read it. This process is reversible, unlike hashing. Encryption is critical for protecting sensitive data from unauthorized access. 𝗘𝗻𝗰𝗼𝗱𝗶𝗻𝗴 This is all about data representation. It converts data from one format to another, making it easier to interpret and display. Common formats: • Base64 • UTF-8 • ASCII Encoding does NOT provide security! It's for data transmission and storage convenience. One common use of hashing is for secure password storage. When you create an account or set a password, the system hashes and stores the password in the database. During login, the system hashes the provided password and compares it to the stored hash without revealing the password.

Make sure it’s clear whether you were leading the project, a key player, or supporting the team. ➤ 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝗶𝗲𝘀 𝗮𝗻𝗱 𝗧𝗼𝗼𝗹𝘀: - Mention the tech and tools you used. This shows your technical know-how and your ability to choose the right tools for the job. ➤ 𝗜𝗺𝗽𝗮𝗰𝘁 𝗮𝗻𝗱 𝗔𝗰𝗵𝗶𝗲𝘃𝗲𝗺𝗲𝗻𝘁𝘀: - Share the results of your project. Did it make things better? How? Mention any improvements, efficiencies, or positive feedback you got. ➤ 𝗧𝗲𝗮𝗺 𝗖𝗼𝗹𝗹𝗮𝗯𝗼𝗿𝗮𝘁𝗶𝗼𝗻: - Talk about how you collaborated. What was your role in the team? How did you communicate and contribute to the team’s success? ➤ 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 𝗮𝗻𝗱 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁: - Reflect on what you learned from the project. What new skills did you gain, and what would you do differently next time? ➤ 𝗧𝗶𝗽𝘀 𝗳𝗼𝗿 𝗬𝗼𝘂𝗿 𝗜𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄 𝗣𝗿𝗲𝗽𝗮𝗿𝗮𝘁𝗶𝗼𝗻: - Be ready with a 30 second elevator pitch about your projects, and also have a five-minute detailed overview ready. - If there’s a pause after you describe the project, don’t hesitate to ask if they’d like more details or if there’s a specific part they’re interested in. By preparing your project details thoroughly and understanding what the interviewer is looking for, you can talk about your experience in a way that really showcases your skills and increases your chances of getting the job.
