Why Is JavaScript NaN Spreading In My Arithmetic? Have you ever experienced unexpected results while working with JavaScript calculations? In this video, we'll explain why NaN (Not a Number) appears and how it can spread through your code. We'll start by defining what NaN is and why JavaScript returns this value during certain operations. You'll learn about common scenarios that lead to NaN, such as dividing zero by zero or multiplying non-numeric strings. We’ll also discuss how NaN behaves when involved in further calculations, often causing entire expressions to become invalid.

If you've noticed NaN showing up unexpectedly, we'll show you how to detect it using the most reliable methods. We’ll explain the differences between isNaN() and Number.isNaN(), and why choosing the right function matters for accurate checks. Additionally, you'll discover practical tips to prevent NaN from spreading by validating inputs early, converting strings to numbers, and handling undefined or non-numeric data properly.

Understanding how NaN propagates in JavaScript is essential for building bug-free web applications, especially in user interfaces, data visualization, or financial calculations. Whether you’re a beginner or experienced developer, mastering these concepts will help you write more dependable code and avoid tricky bugs. Join us to learn how to identify, prevent, and manage NaN effectively in your projects.
