When exceptions occur, it is usually a bad idea to simply ignore them. Instead, it is better to handle them properly, or at least to log them.
Noncompliant code example
function f() {
  try {
    doSomething();
  } catch (err) {
  }
}
Compliant solution
function f() {
  try {
    doSomething();
  } catch (err) {
    console.log(`Exception while doing something: ${err}`);
  }
}
