Secondly, not everything must be typed explicitly - TypeScript is very smart and can deduce types for us. Firstly, if we would not comply with declared types, TypeScript would alarm us that something is wrong and prevent misuse.

There are additional things about this example that you should know.

Finally, we create new variable with information whether justine is an adult or not. After this we create justine, our example data that can be used for calling previously defined function. Later we utilize this newly created type to create function isAdult that accepts one argument of type User and returns boolean.

Take a look at this code snippet and then we can unpack it together:įirst part with type keyword is responsible for declaring our custom type of objects representing users. We can talk about other TypeScript benefits later, let's see some examples now! Examples It makes our code more secure and robust by preventing a lot of bugs before code is even shipped - it catches problems during writing the code and integrates wonderfully with code editors like Visual Studio Code. TypeScript is a really powerful tool and opens new world of possibilities in JavaScript projects. Thanks to types, it's possible, for example, to declare what kind of arguments we are expecting and what is returned exactly in our functions or what's the exact shape of the object that we are creating. Most notable addition are static type definitions, something that is not present in plain JavaScript.

I like to use the Integrated Terminal Window inside Visual Studio Code, just because it’s there and it runs commands scoped to the project directory I’m in.
