Modern Web Design with HTML5, CSS3, and JavaScript - Getting the Data Type Using the JavaScript Code - Coding Challenge

The video tutorial guides students through a JavaScript challenge where they must convert a string input from a prompt into a number to perform arithmetic addition instead of string concatenation. The instructor explains the problem of concatenating strings when using the '+' operator and demonstrates how JavaScript can automatically convert types in certain operations like multiplication. The solution involves explicitly converting the string to a number using the 'Number' function to ensure correct arithmetic operations.
