Running javascript from a bash script

Question

I am new to learning bash script programming and was wondering if anyone here knows how can I execute javascript that would normally be embedded into an html page?

So from a bash script, I would like to execute ( for example ):

<script type="text/javascript" src="scriptName.js"></script>

Thank you very much for anyone's help.

You'll need a Javascript runtime like Node.js.

To evaluate a snippet of code: $ node -e "console.log('hello')"

To run a script: $ node script.js

How about using env like:

my-file

#!/usr/bin/env node

console.log("hello from test file");

Make the file executable.

chmod +x my-file

Then run it:

node my-file
hello from test file

I did run the script directly without calling node at first like this: ./myfile.js

Yeah. I 2nd that. You don't have to use node after you supply the REPL.
