does Jscript on windows really exist??

I read on various web pages that jscript can be used on windows as a scripting language directly form the DOS prompt. But I couldn't find ANY working example on the internet! even a simple alert("hello") put in a hello.js file doesn't work! It says an object is missing. Now I tried to find info on the web and after many attempts I am starting to doubt if this is just hype.

Can I really run A SIMPLE alert("www") in a hello.js file from the DOS prompt without any errors ? does this jscript thing really exist ?

(I also tried c:> cscript hello.js and others but to no avail... Thanks if anyone knows anything about this.

Problem is the exact case of the string WScript.

(notice the WS...)


var a=new Array(10000);

for(i=1;i<10000;i++)a="www"+i;

WScript.echo (a[4877]);

for(i=999;i<1010;i++) WScript.echo (a);


It seems that some syntax is invented just to confuse; in vbs all cases work, in js not so, maybe to discourage a newbie to use js ... and then why didn't they maintain the alert() function ?

Anyways you can use this quick and dirty programming language on any PC right off the bat, just save the program as .js and run from the command line.
or run as cscript hello.js to see results as console.

Yes, Jscript does exist on Windows as a scripting language. It is a Microsoft implementation of the ECMAScript standard, which is also used by JavaScript. Jscript can be used for scripting tasks on Windows, such as automating tasks or creating scripts for webpages.

However, it is possible that the example you found on the internet was not working due to syntax errors or incorrect usage. It is also important to note that Jscript is not commonly used in modern web development and has been largely replaced by JavaScript. So, while it does exist, it may not be as widely used as it once was.

If you are having trouble getting Jscript to work, I suggest consulting documentation or seeking help from experienced programmers. It is possible that the issue lies with your code or setup, rather than Jscript itself not existing.
