You'll create, access, and modify objects to build a solid foundation for object-oriented programming.Functions at RuntimeFunctions are one of most important data structures. Learn what a "first-class function" is, learn about scope, dig into closures, and use immediately-invoked function expressions for private state.Classes and ObjectsCreating objects individually isn't sustainable. Learn how to create similar objects with ease using Classes. You'll also learn how object inheritance works through Prototypal Inheritance.Object-Oriented Design PatternsDiscover object-oriented design patterns that can be used to create an object -- all without involving its prototype. What's more: you'll also learn how to implement private properties in objects.CompanyAbout UsWhy Udacity?BlogIn the NewsJobs at UdacityBecome a MentorPartner with UdacityResourcesCatalogCareer OutcomesHelp and FAQScholarshipsResource CenterFeatured ProgramsBusiness AnalyticsSQLAWS Cloud ArchitectData AnalystIntro to ProgrammingDigital MarketingSelf Driving Car EngineerOnly at UdacityArtificial IntelligenceDeep LearningDigital MarketingFlying Car and Autonomous Flight EngineerIntro to Self-Driving CarsMachine Learning EngineerRobotics Software EngineerAI Master’sMaster of Business AdministrationMaster of Science in AIUdacity SchoolsSchool of Animation and Game DevelopmentSchool of Artificial IntelligenceSchool of Autonomous SystemsSchool of BusinessCareer ResourcesSchool of Cloud ComputingSchool of CybersecuritySchool of Data ScienceSchool of DevOpsSchool of Executive LeadershipSchool of Product ManagementSchool of Programming and Development
