Public Members
In TypeScript, the public access modifier is used to specify that a class property or method can be accessed from anywhere: inside the class, by instances of the class, and even from code outside the class. In fact, if you do not explicitly specify an access modifier for a class member, TypeScript treats it as public by default. This means your class members are open for access unless you intentionally restrict them.
12345678910111213class Car { public make: string; public model: string; public start(): void { console.log(`${this.make} ${this.model} is starting.`); } } const myCar = new Car(); myCar.make = "Toyota"; myCar.model = "Corolla"; myCar.start(); // Output: Toyota Corolla is starting.
Using public members is useful when you want to allow other parts of your code to interact freely with your class. For example, if you are building a data model where all properties should be accessible and modifiable, declaring them as public makes your intent clear and keeps your code straightforward. However, you should use public members thoughtfully to avoid exposing implementation details that might be better kept private or protected in future code changes.
