Splice() function is not working

JavaScript

Tell us what’s happening:
Hello, I am getting an error saying that my .splice() is not a function. Here are the instructions:
Truncate a string (first argument) if it is longer than the given maximum string length (second argument). Return the truncated string with a ... ending.

  **Your code so far**


function truncateString(str, num) {
let slicedIt = str.slice("");
let splicedIt = slicedIt.splice(0, num, "...");
return splicedIt.join();
}

console.log(truncateString("A-tisket a-tasket A green and yellow basket", 8));

splice is an array method, you can’t use it on a string
