javascript - Baby steps Node.js program prints indeterministic results -


I'm working on "learnyounode", the baby step of interactive Node.js tutorial.

is a program that accepts one or more number of commands line arguments and console (stdout).

Since I already know javascript, I thought it would be rather simple to print the sum of those numbers: 

  var sum = 0; For (var i = 2; i & lt; process.argv.length; i ++) {console.log ('add' + process.argv [i]); Zodiac + = number (process.argv [i]); } Console.log (sum)

I can not see any problem in this piece of code, but the result seems unavoidable to me!

What's going on here? I am using Node.js v0.10.34 on Windows 7.

itemprop = "text">

learnyounode after its own arguments in the functionality (which you Do not know) without asking and ignoring their own arguments.

You would say good ol 'node executable to play your file: 

  node baby_steps.js
learnyounode instead of calling execution

: 

  run learnyounode baby_steps.js
