We begin the discussion of object-oriented programming by discussing the syntax and use of object literals. Object literals are not instances of classes; they stand on their own.
- [Instructor] Let's turn our attention…to object literals, classes, and interfaces.…Traditionally, for JavaScript programmers,…this is the hard part, but as C# programmers,…this is our bread and butter.…TypeScript supports the creation of object literals.…Notice that this object literal defines two properties…with their values, but also defines a method area,…which returns the height times the width.…The type of this object literal is inferred.…Or you can explicitly define the rectangle…to be of typed object and notice the capital O.…

1/5/2017In this course, Jesse Liberty reviews the fundamentals of TypeScript for the C# developer, including the built-in types, flow controls, and functions. He covers default, optional, and rest parameters; lambda functions; object literals; and the creation and use of custom classes. Plus, learn about other object-oriented features such as inheritance and interfaces. By the end of the course, C# developers should be well on their way to incorporating this flexible and powerful web programming language into their app development workflow.
