Tell us what’s happening:

Getting a TypeError: str.slice is not a function. can someone explain why this isn’t working?

Your code so far

const truncateString = (str,num)=> {
  let shortString = str.slice(0,num);
  let truncate = shortString + "...";
  if (str.length >= num && str.length){
    return truncate}
     
  else if (str.length <= num){
    return str
  }  
};

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

Welcome to the forum @bbtall

When I remove the function, but leave the argument, in the console log I see only one argument.

The truncateString takes two parameters.

Happy coding

Right! it should be ;
console.log(truncateString(“A-tisket a-tasket A green and yellow basket”,“A-tisket a-tasket A green and yellow basket”.length));

and then it returns ;

A-tisket a-tasket A green and yellow basket…

but I am only wanting it to console.log “A-tisket a-tasket A green and yellow basket” and I am seeing that I need to added a 3rd condition on the if else statment, but haven’t figured that out yet.
