string-prototype-trim()-example.js
const myString = " Hello world! ";
console.log(myString.trim()); // The leading and trailing whitespace are removed: "Hello world!"
console.log(myString); // The original string remains unchanged: " Hello world! "
// String.prototype.trim() is used with a . (dot-reference operator), not:
trim(myString);
// This would result in "ReferenceError: trim is not defined"
