Private methods in a class
In TypeScript, you can add private methods to a class using the private access modifier. A private method can only be accessed from within the class in which it is defined. Here’s an example:
class MyClass {
// Public method
public greet(): void {
console.log("Hello, world!");
this.sayHello(); // Calling the private method within the class
}
// Private method
private sayHello(): void {
console.log("This is a private method.");
}
}
const instance = new MyClass();
instance.greet(); // Works fine
// instance.sayHello(); // Error: Property 'sayHello' is private and only accessible within class 'MyClass'.
