Introduction to Computer Science

The benefits of taking free online courses offered by universities are numerous.

First of all, it's a great way to learn about a variety of topics. Second, you can learn at your own pace and in your own time. Third, you can learn from anywhere in the world. And fourth, you can often earn college credit for taking such courses.

However, with the ubiquity of the Internet, there are now many free online courses offered by universities that allow people to learn at their own pace and on their own time.

These courses are often just as comprehensive and challenging as their physical counterparts, and provide a great way to learn new things or improve existing skills.

Course description

This course picks up where CS50 leaves off, transitioning from web development to mobile app development with React Native.

The course introduces you to modern JavaScript (including ES6 and ES7) as well as to JSX, a JavaScript extension. Through hands-on projects, you'll gain experience with React and its paradigms, app architecture, and user interfaces. The course culminates in a final project for which you'll implement an app entirely of your own design.

Course description

This is CS50x , Harvard University's introduction to the intellectual enterprises of computer science and the art of programming for majors and non-majors alike, with or without prior programming experience. An entry-level course taught by David J. Malan, CS50x teaches students how to think algorithmically and solve problems efficiently. Topics include abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and web development. Languages include C, Python, SQL, and JavaScript plus CSS and HTML. Problem sets inspired by real-world domains of biology, cryptography, finance, forensics, and gaming. The on-campus version of CS50x , CS50, is Harvard's largest course.

Students who earn a satisfactory score on 9 problem sets (i.e., programming assignments) and a final project are eligible for a certificate. This is a self-paced course–you may take CS50x on your own schedule.
