A Final Word

In this column we showed how to handle run-time exceptions in Internet Explorer 5's new JavaScript. We demonstrated several examples of the try...catch statement in JavaScript. We highlighted the differences and similarities between JavaScript and the other programming languages, C++, Java, and VBScript. We tried to give you the sense that JavaScript has gone up a class by the addition of the exception handling mechanism. We also tried to convince you that JavaScript's exception handling is superior to that of VBScript. In this column you learned:

• How to write an exception-handling code for JavaScript-thrown exceptions.
• How to write an exception-handling code for user-thrown exceptions.
• How to write an exception-handling code for handling user-thrown exceptions in a real application.
• How to distinguish between JavaScript's exception handling and C++'s and Java's.
• How to distinguish between JavaScript's exception handling and VBScript's.
• How to workaround inconsistencies between JavaScript and VBScript.
