What is a hackathon?

At CS4ALL hackathons, students from all over New York City are challenged work together to reimagine their communities and how technology gets used. Hackathons are ideal for honing new or familiar programming languages as students work in fresh and exciting environments, learning how to rapidly prototype ideas and create working demos, as well as develop and present their ideas to judges and other students.

Thinking of attending a CS4ALL hackathon? Look at these recaps and pictures from our past hackathons.
