Undefined vs Null in TypeScript: What’s the Difference?

1. 1Declare a variable without assigning a value to see how TypeScript treats it as undefined
2. 2Assign null to a variable and observe the differences in behavior
3. 3Use the typeof operator to check the type of a variable and distinguish between undefined and null
4. 4Apply the optional chaining operator (?.) to safely navigate through nested objects and avoid null pointer exceptions
5. 5Test the difference between undefined and null using a simple if-else statement

Developers working with TypeScript will benefit from understanding the distinction between undefined and null to write more robust and error-free code. This knowledge is essential for collaboration and code review.

💡 In TypeScript, undefined represents an uninitialized variable, while null represents the absence of any object value
