Why isn't my code running in Sublime Text 3 and Atom?

JavaScript

In Sublime Text 3 I try to run the code:

function largestOfFour(arr) {
return arr;
}

console.log(largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]));

Then I click on “Build” and the code doesn’t run. Why isn’t it running and how to I Make it run?

The same problem happens with Atom, I install the package “Script” then when I press “Build” is doesn’t run and says “The system cannot find the file specified.[Finished in 0.479s]”.

I Saved it as “.js”.

I don’t use either of those but the code works fine in http://pythontutor.com/javascript.html

You could try making a html file and onload of body run the script file.

It should work on Atom and Sublime just like this online editor. I’m trying to figure that out. Why is it not working!

You mean like these codes? https://www.guru99.com/practical-code-examples-using-javascript.html and save it as HTML?

It also doesn’t work!

This is how I do it:

What don’t you get?
Did you “view source”?

JavaScript is a language interpreted by the web browser. Or that’s how it was designed. It works with the HTML (markup language) to add extra functionality on the client side.
