Date: 2012feb23 Updated: 2020oct8 OS: Linux Language: javaScript Keywords: test, check, syntax Q. Is there javaScript for command-line Linux? A. Yes. To install on RedHat/Fedora/CentOS:

dnf install nodejs

To use, put some javaScript code in a file (eg myfile.js) and run:

node myfile.js

I find this very handy. You can check the syntax of code that you might use on a website. There used to be package called just "js" which was Mozilla SpiderMonkey but its not an available package any more. You can still build it from source.
