 // The error is occurring because we are trying to declare a variable 'str' inside the function that has the same name as the parameter 'str'.To fix this problem,  create an variable with a new name Newstr . So we would change the line to: Newstr = `${str[0].toUpperCase()}${str.slice(1)}`; 
 // =============> write your new code here
  function capitalise(str) {
-  let Newstr = `${str[0].toUpperCase()}${str.slice(1)}`;
-  return Newstr;
+  let newStr = `${str[0].toUpperCase()}${str.slice(1)}`; //change the variable name to newStr to conform with camelCase name convention.
+  return newStr;
 } 
 console.log(capitalise("hello world"));
