The React Nanodegree program is comprised of 3 courses and 3 projects. Each project you build will be an opportunity to demonstrate what you’ve learned in your lessons. Your completed projects become part of a career portfolio that will demonstrate your mastery of React to potential employers.
In addition to the code reviewed projects of this Nanodegree program, you also have access to mentors in the classroom, a community of students to learn alongside, and career search support from Udacity.
