Udacity Nano Degree?

I'm interested in getting a job as a Front-End Developer... How realistic is it that I will get hired with this a nano degree from udacity?

Is it better to take the traditional route i.e. local community college or university?

Udacity courses typically take 6 months to complete whereas a community college is 9 months to 1 year. The cost is about the same Seattle Community College averages about $2k for the year and Udacity is about $1800 for the program.
