In this video on Code with Tanvi, we solve a common JavaScript coding interview question: finding missing numbers from an array.

Interviewers often ask this problem to test your understanding of arrays, loops, and logic building.

We use a simple approach with a loop and the includes() method to identify which numbers are missing from a given range.

Topics covered:
• Finding missing numbers in an array
• Using for loop in JavaScript
• Understanding includes() method
• JavaScript interview preparation

Example:
Array: [1, 2, 4, 6, 7, 9]
Range: 1 to 10

Output:
[3, 5, 8, 10]

If you're preparing for coding interviews or learning JavaScript, this video will help you understand the concept clearly.
