Check Domain Availability

My first node.js app! feedback/suggestions/changes appreciated

this app does the following

1. generates 3 letter domain names (up to a specified limit)
2. calls NameCheap api in batches
3. shows which of the generated names are available

usage:

git clone https://github.com/squarewave24/Node-Domain-Availability-Checker.git

cd Node-Domain-Availability-Checker

node run.js

• you'd need to create a developer account on namecheap to get the apikey and add your client ip http://www.namecheap.com/support/api/api.aspx
