This repository demonstrates a common error in JavaScript related to handling null values. The bug.js file contains code with a flaw in null value handling. The bugSolution.js file provides a corrected version. The core issue is the potential for unexpected results when null values are not explicitly checked for.
The original code lacked proper checks for null inputs, leading to unexpected behavior or runtime errors in certain scenarios. The improved version incorporates strict equality checks (===) to explicitly handle null values, resulting in more robust and predictable behavior.
Explicitly checking for null values using === and returning an appropriate value (in this case, null) prevents unexpected behavior and ensures the function handles all possible input scenarios correctly.
