Exceptions in asynchronous code in JavaScript

An exception thrown inside asynchronous code cannot be caught via try-catch:

try { setTimeout(function() { throw(new Error); // an exception will not be caught }, 3000); } catch(error) { console.log(error); }

Tell me what is the problem of the following code:

try { elem.addEventListener('click', function() { JSON.parse('some string'); }); } catch() { console.log('invalid json'); }
