<ul data-eligibleForWebStory="true"><li>JavaScript has hidden bugs that can easily creep into your code, challenging even experienced developers.</li><li>Common bugs include `NaN`, type coercion with loose equality operator, hoisting, and the dynamic behavior of `this`.</li><li>To check for `NaN`, use `isNaN()` or `Number.isNaN()`, not typical equality checks like `=== NaN`.</li><li>Always use strict equality operator (`===`) to prevent type coercion issues.</li><li>Avoid hoisting bugs by using `let` or `const` instead of `var`.</li><li>JavaScript's `this` behavior can lead to unexpected bugs; use arrow functions or explicit binding to manage it.</li><li>Be cautious with floating-point arithmetic to prevent rounding errors; consider using `toFixed()` or `Math.round()`.</li><li>Objects in JavaScript are reference types, so be aware of unintended side effects when mutating objects.</li><li>When working with asynchronous code inside loops, using `setTimeout` can lead to unexpected results.</li><li>Understanding these hidden bugs in JavaScript can help developers write cleaner and more reliable code.</li></ul>
