The difference becomes obvious when we look at the code inside a function. The behavior is different if there's a "jump out" of try...catch.. For instance, when there's a return inside try...catch.The finally clause works in case of any exit from try...catch, even via the return statement: right after try...catch is done, but before the calling code gets the control.

Technically you can throw an exception (throw an error). The exception can be a JavaScript String, a Number, a Boolean or an Object: throw "Too big"; // throw a text. throw 500; // throw a number. If you use throw together with try and catch, you can control program flow and generate custom error messages. When an exception occurs the call stack only shows the line number of the statement in the catch, not the actual line number of what caused the exception. This makes it very difficult to track down where the exception accually occured. The exception object doesn't seem to have the line number in it either. The parseInt function converts its first argument to a string, parses that string, then returns an integer or NaN. If not NaN, the return value will be the integer that is the first argument taken as a number in the specified radix. (For example, a radix of 10 converts from a decimal number, 8 converts from octal, 16 from hexadecimal, and so on.)

If no catch block exists among caller functions, the program will terminate.
