When an error is caught, will the code continue or move to the next iteration?
Continuation of loop with try and catch:
for (let count = 0; count < 10; count++)
{
try
{
if(count == 6)
{
document.getElementById('noid').html("x"); //this will trigger an exception because there is no element with that ID
}
console.log("In try Iteration :: "+count);
}
catch (error)
{
console.log("In catch Iteration :: "+count);
}
}The main purpose of try and catch is to maintain program execution even if an exception occurs instead of abruptly halting the process.
