By using Type Annotation
Type annotation involves explicitly stating the data type of a variable or property.
Example: Here, we use the : number type annotation to specify that myIntegerProperty should be of type number. We create an instance of MyClass and log the value myIntegerProperty to the console.
Javascript
class MyClass { myIntegerProperty: number; constructor(value: number) { this.myIntegerProperty = value; }}const myInstance = new MyClass(5);console.log(myInstance.myIntegerProperty); |
Output:
5
