Prototype is intimately tied to constructors so calls to prototype only works on a constructor function (for example Fruit)

Prototype is more memory efficient (50 copies of the eat function for 50 fruit instances) but could be harder to read and maintain

Prototype works in a delegation fashion

If this is your first install, automatically load on login with:
    mkdir -p ~/Library/LaunchAgents
    cp /usr/local/Cellar/mongodb/1.8.2-x86_64/org.mongodb.mongod.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/org.mongodb.mongod.plist

If this is an upgrade and you already have the org.mongodb.mongod.plist loaded:
    launchctl unload -w ~/Library/LaunchAgents/org.mongodb.mongod.plist
    cp /usr/local/Cellar/mongodb/1.8.2-x86_64/org.mongodb.mongod.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/org.mongodb.mongod.plist
