Error handling with callbacks is especially interesting, try this code -
the 'Surprise' error won't be caught.
// Catching synchronous errors.
try {
myFunction(function(err){
// Catching asynchronous errors.
if(err) return console.log('error catched')
console.log('no errors')
})
} catch(err) {
console.log('error catched')
}
var myFunction = function(cb){
setTimeout(function(){
someFunctionDeepInLibrary(cb)
}, 100)
}
var someFunctionDeepInLibrary = function(cb){
throw new Error("Surprise!")
}
