How to run JavaScript using jsc on OS X?

Question

I got this when I was trying to find some way to run my JavaScript programs through terminal. The run and load command mentioned can execute external JavaScript files. Help me how to do this. I am trying to run JavaScript programs which are store locally on my system.

EDIT: I am trying to solve Project Euler Q10 in JavaScript. So this is the program that I want to run in NodeJs or JSC. I need help in running the JavaScript files in Node and JSC. Any example will be really helpful.

Thank You all.

Answer 1

Complements of this post, JSC lives at

/System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc 

and is not in the shell PATH by default. You can fix that with

ln -s /System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc /usr/local/bin 

jsc takes filenames as arguments. You could run a file named demo.js with

jsc demo.js 

Note that you'll have to use debug() instead of the conventional console.log() in your script to see any output.

NOTE for MacOS Catalina (10.15.x) users

jsc now lives on a new path:

/System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Helpers/jsc 

Make that adjustment to @hurrymaplelad's instructions and you'll be good to go.
