🔢 Struggling with numbers in JavaScript? This ultimate guide covers number handling from basic operations to advanced quirks like NaN, Infinity, and floating-point precision!
📌 What You’ll Learn:
✔ Number declaration (literals vs. constructor)
✔ Safe integer limits (Number.MAX_SAFE_INTEGER)
✔ NaN detection and handling (isNaN() vs Number.isNaN())
✔ Floating-point precision issues (0.1 + 0.2 ≠ 0.3 explained)
✔ BigInt for massive numbers (ES2020 feature)
✔ Type conversion tricks (string ↔ number)
💻 Try It Yourself:
console.log(0.1 + 0.2); // Spoiler: It's not 0.3!
🔗 Essential Resources:
- MDN Number Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number
