Welcome to the form @olga.murzha

let text = "Hello, JavaScript world!";
let result = text.includes("JavaScript", 8);

console.log(result) // false

The second parameter in the includesmethod is for the starting index.

Hello, Jav
0123456789

Any number above 7 will assign false to the resultvariable.

Happy coding
