Скачать или смотреть Truthy & Falsy Values Are BREAKING Your Code! Here's Why

Your if-statements are lying to you. Right now, there are bugs hiding in your code caused by truthy and falsy values — and you probably don't even know it.
In JavaScript, values like 0, "" (empty string), null, undefined, NaN, and false are all FALSY meaning they evaluate to false inside conditions. But here's the problem: sometimes 0 is a valid value. Sometimes an empty string is intentional. And when your if-statement silently treats them as false, your entire logic breaks without any error message.
In this video, I'll show you exactly how truthy and falsy values work, the most common pitfalls developers fall into, and how to write bulletproof conditions that handle every edge case.

🔥 What You'll Learn:
✅ What are Truthy & Falsy values in JavaScript
✅ The complete list of ALL falsy values
✅ Why 0 and "" silently break your if-statements
✅ The difference between null and undefined in conditions
✅ Why NaN is the sneakiest falsy value
✅ Common real-world bugs caused by truthy/falsy confusion
✅ == vs === and how it makes things worse
✅ How to write safe null checks and default values
✅ The Nullish Coalescing Operator (??) vs OR (||)

⚡ Fun Fact:
There are only 8 falsy values in JavaScript: false, 0, -0, 0n (BigInt), "", null, undefined, and NaN. EVERYTHING else is truthy — including empty arrays [] and empty objects {}! Mind blown? 🤯
