How to get a random element from an array in JavaScript?

Hello everyone! I'm new to JavaScript and ran into a problem. I have an array with user names: ```javascript const users = ['Anna', 'Boris', 'Victor', 'Galina', 'Dmitry']; ``` I need to write a function that will return a random name from this array. I know that JavaScript has `Math.random()`, but I don't understand how to apply it to an array. I tried doing this: ```javascript function getRandomUser() { const randomIndex = Math.random(); return users[randomIndex]; } ``` But it doesn't work — it returns `undefined`. I understand that `Math.random()` returns a number from 0 to 1, not an array index. How do I correctly convert a random number into an index? I'm also interested in how to make the function work with any array, not just
