Topics include database design, scalability, security, and user experience. Through hands-on projects, students learn to write and use APIs, create interactive UIs, and leverage cloud services like GitHub and Heroku. By semester’s end, students emerge with knowledge and experience in principles, languages, and tools that empower them to design and deploy applications on the Internet. *** This is CS50, Harvard University's introduction to the intellectual enterprises of computer science and the art of programming. *** HOW TO SUBSCRIBE https://www.youtube.com/user/cs50tv?sub_confirmation=1 HOW TO TAKE CS50 edX: https://cs50.edx.org/ Harvard Extension School: https://cs50.harvard.edu/extension/2024/spring/ Harvard Summer School: https://cs50.harvard.edu/summer/2024/ OpenCourseWare: https://cs50.harvard.edu/x/2024/ HOW TO JOIN CS50 COMMUNITIES Discord: https://discord.com/invite/cs50 Ed: https://edstem.org/us/join/gEcnkZ Facebook Group: https://www.facebook.com/unsupportedbrowser Faceboook Page: https://www.facebook.com/unsupportedbrowser GitHub: https://github.com/cs50 Gitter: https://app.gitter.im/#/room/#cs50_x:gitter.im Instagram: https://www.facebook.com/unsupportedbrowser LinkedIn Group: https://www.linkedin.com/uas/login?session_redirect=https%3A%2F%2Fwww.linkedin.com%2Fgroups%2F7437240%2F LinkedIn Page: https://www.linkedin.com/school/cs50/ Medium: https://cs50.medium.com/ Quora: https://www.quora.com/topic/CS50 Reddit: https://www.reddit.com/r/cs50/ Slack: https://cs50x.slack.com/join/shared_invite/zt-2jgh5lhhj-jXrSnGbmhcFYnCeHVstIqg Snapchat: https://www.snapchat.com/add/cs50 SoundCloud: https://soundcloud.com/cs50 Stack Exchange: https://cs50.stackexchange.com/ TikTok: https://www.tiktok.com/@cs50 Twitter: https://twitter.com/cs50 YouTube: https://www.youtube.com/cs50 HOW TO FOLLOW DAVID J.
