Should I always test JS in the browser?

Question

I'm a beginner js. My question is: should we always use a browser to test JS code? Is there an avilable command line compiler / interpreter?

Answer 1

Rhino and Spidermonkey provide standalone interpreters, but you will need to find a DOM implementation if you want to test DOM manipulation, and you need to test in any browsers that you aim for (not all JS engines are created equal).

Answer 5

Yes you should. Since the standard is not respected, each browser may behave depending on your code. Therefore, it is better to check it in browsers.
