Syntax new Error([message[, fileName[, lineNumber]]]) Parameters message Optional. Human-readable description of the error. fileName Optional. The value for the fileName property on the created Error object. Defaults to the name of the file containing the code that called the Error() constructor. lineNumber Optional. The value for the lineNumber property on the created Error object. Defaults to the line number containing the Error() constructor invocation. Description Runtime errors result in new Error objects being created and thrown. This page documents the use of the Error object itself and its use as a constructor function.

The JavaScript Error Handling: Why You Need it article outlined some of the major reasons why you need to consider error handling sooner rather than later in a Web application's development cycle. Everyone knows that error handling is javascript errors in important, but to what end? In fact, error handling plays many roles, from reassuring the end-users, to helping identify trouble spots in an application, to siphoning off potential security holes in the code. In this installment on error handling in JavaScript, we'll be taking a look at how to code your exception handling in JavaScript in a way that takes browser discrepancies into account. Anatomy of the Try/Catch Block In all browsers, the mechanism of choice for trapping errors is the Try/Catch block. As the name suggest, the Try/Catch Block is made up of two sections. The try {} encloses code in which to trap exceptions; the catch {} section contains code to deal with the error: try { eval("var " + varName + "=" document.inputForm.txtVal); } catch (e) { console.log("An exception occurred in the script."); } It all seems so easy. However, there is a glitch in the above code; Internet Explorer doesn't recognize the console object. The alternative of using the fully supported alert box is tempting, but don't do it! The whole point of catching errors in the first place is to get rid of those annoying popups that appear every time an error fires. Instead, consider writing error messages to a designated part of the page or, in the cas
