The try keyword
The try keyword is used to be sure that a number of commands to follow will not cause an unhandled exception. If one of the lines causes an exception, the code inside the catch clause will be executed. If the try statement does have a finally clause, this part will execute irrespective of what happened before.
Examples
The code
try {
log(-12.05);
alert("Executed comment successfully.");
} catch(err) {
document.getElementById("demo").innerHTML = err.message;
} finally {
alert("Try finished.");
} (Will add to the HTML element called "demo" the error message. An alert window with the text "Try finished." will appear.)
