This seems good, I need some comments about using eval for this purpose. Although i think it wont exactly fit there. But there might be an alternative.<br />
The reason is i dont have to include and separate library in my code if this approach succeeds thereby lowering the page load time.

Hi,<br />
I need to make a javascript code which will parse a javascript file and tell me whether this is a valid javascript program or not. Are there any tools or libraries available to do so ? <br />
Also i guess eval() function can be used to do it. But it could be dangerous as i have read on some websites... <br />
I am bascially planning to embed the javascript parser on my web application and so whatever code the users puts in there my parser will parse it and tell whether its a valid javascript file or not.<br />
Please provide some tips... A parser may not be even required probably if i could use eval statement ... or something similar. It will do the job out of the box without writing anything.<br />
<br />
Thanks

Making a javascript parser in javascript language

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

JavaScript

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.

Programming

A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.

Programming Languages-Other

A miscellany is defined as a "collection of various pieces of writing by different authors", but it has come to mean something "Of items gathered or considered together of various types or from different sources" or "a collection or group composed of members or elements of different kinds". The word "miscellaneous" comes from the Latin word "miscere", meaning "to mix." You might have heard the expression "a mixed bag," which applies when you don't quite know what you're going to get. More commonly, a miscellaneous group is made up of an odd group of things that don't fit anywhere else.
