Substring to search for. If the method is called with no arguments, searchString is coerced to "undefined". Therefore, 'undefined'.indexOf () returns 0 — because the substring "undefined" is found at position 0 in the string undefined. But 'undefine'.indexOf (), returns -1 — because the substring "undefined" is not found in the string "undefine". Problem Solution 1. Take a string and a substring from the user and store it in separate variables. 2. Check if the substring is present in the string using find () in-built function. 3. Print the final result. 4. Exit.
