Online typescript compiler5/28/2023 TypeScript also includes features such as interfaces, classes, and decorators, which can be used to create more robust and scalable applications. The greet function returns a string that includes the value of the name parameter. This tells TypeScript that the name parameter should be a string. In this example, the greet function is defined with a single parameter, name, which is annotated with the string type. Here is a simple example of a TypeScript program:Ĭopy codefunction greet(name: string) console.log(greet('TypeScript')) // Output: "Hello, TypeScript!" TypeScript can be used with any JavaScript library or framework, and is often used in conjunction with Angular, a popular web development framework developed by Google. This can make it easier to catch bugs and understand larger codebases, as the type system helps you keep track of the shape of your data. TypeScript adds optional static typing and class-based object-oriented programming to the JavaScript language. It is a typed superset of JavaScript that compiles to plain JavaScript. TypeScript is a programming language developed and maintained by Microsoft.
