exercise 2

[Stephany Prodromos]

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??

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.
