What are considered the types of access modifiers supported by TypeScript?PublicPrivateProtectedAll of the above

1. Break Down the Problem

The question asks for the types of access modifiers in TypeScript and provides multiple-choice options: Public, Private, Protected, and All of the above.

2. Relevant Concepts

In TypeScript, access modifiers are keywords that set the accessibility of class members (properties and methods). The main types of access modifiers in TypeScript are:

• Public: Members are accessible from anywhere.
• Private: Members are accessible only within the class.
• Protected: Members are accessible within the class and by subclasses.

3. Analysis and Detail

• Public: If a member is declared with the public keyword, it can be accessed from any other code. By default, all members are public if no access modifier is specified.
• Private: Members declared as private cannot be accessed from outside the class, meaning they are encapsulated and intended for internal use only.
• Protected: Members declared as protected can be accessed within the class and by instances of subclasses, but not by instances of other classes.

4. Verify and Summarize

Since all three access modifiers (Public, Private, and Protected) are indeed supported by TypeScript, the option All of the above is correct. This means that all presented access modifiers are valid and part of TypeScript's capabilities.

Final Answer

The correct answer is All of the above. TypeScript supports Public, Private, and Protected access modifiers.
