Typescript : Object is possibly null

Question

How to avoid Object is possibly null in VSCode though code runs ok

  let url = 'https://test.com/test/varstring/stringtoextract?id=test3'
  let regex = /https://test.com/test/varstring/.+/(.+)?.+/
  var match = regex.exec(url);
  alert(match[1]);

Answer 1

If you are sure, use the Non-null assertion operator !:

alert(match![1]);

Of course, an if statement would also do the trick:

if (match) {
    alert(match[1]);
}
