JavaScript: Console not logging without error message

Question

I made a simple function to illustrate my problem

I ran this code on Windows Powershell with Node.js, not on a browser. It doesn't log anything to the console. What am I doing wrong? I was just goofing around testing stuff. This is the only code in the file, nothing else.

 var sigma = function(nums) { var i = 0; var ops = nums.length - 1; var sum = 0; while (i <= ops) { sum += nums[i]; i += 1; } console.log(sum); }; sigma([1, 2, 3, 4, 5]);

Answer 1

Did you install node in your environment?

I means for javascript code you need to first compiled it.

Maybe after installing node environment, You need run it
