You can use a for loop for this:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/
Reference/Statements/for

Use the initialization expression to set the index you want to start at
(var i = 2) then test for the end of the array (i < process.argv.length) in
the condition expression, increment the index in the "final" expression,
and add the value at each index to a running total in the block statement.

Hope that helps. I left out the specific code so you could learn it on your
own, but if you just want to see the code that does it, let me know.

Hi guys I just started learning node today, and am a little confused as to
how to go about the second exercise....

at first i had:

var num1 = +process.argv[2];
var num2 = +process.argv[3];
var result = num1 + num2;

console.log(result);

...but this will only work for 2 numbers. any ideas on how to loop through
process.argv to account for multiple number inputs??
