Here's a collection of tips, tricks, and stories from my coding journey, designed to help you enhance your skills and stay updated with the latest in web development.
Frontend validation improves user experience. It shows instant errors and prevents obvious mistakes like empty fields or invalid email formats. But frontend validation is never security. Anyone can bypass it using DevTools, Postman, or by directly calling your API. That’s why backend validation is mandatory it protects your database and business logic from invalid or malicious data.
Before mastering Flexbox or Grid, you must understand how CSS calculates size.
clamp() lets text scale smoothly between a min and max size based on screen width—without media queries.
Type guards tell TypeScript what the value really is.
unknown is safer than any. It forces you to validate the type before using it.
Both methods run multiple promises in parallel, but they differ in how they handle errors. Choosing the right one prevents bugs and missing data in real-world apps.
Optional chaining (?.) allows you to safely access nested object properties without throwing errors if any property in the chain is null or undefined. This eliminates the need for verbose null checks and prevents runtime crashes.
The nullish coalescing operator (??) provides a fallback value only when the left side is null or undefined, unlike the logical OR (||) which treats all falsy values (0, '', false) as requiring the default.
