Task: Calculator that adds two numbers together
input -> logic -> output
input - putting stuff into a command line
logic - turning numbers into something (talks to an API, or a database)
output - spit data onto a console
command line works -> sum (nums) -> num -> console.log(num)
#Research
Google: node command line argument
console.log
Sums example - debugging - ignoring strings in number functions
//input //logic - sum = (numbers[] = number) - will ignore non numeicr input
function sum(nums){ var runningSum = 0
for(var i=2; i < nums.length; i++){ if(!isNaN(nums[i])){ runningSum = runningSum + Number(nums[i]); } } return runnningSum }
//output
console.log(sum(process.argv));
