    Which Object Oriented Terms are Supported by Typescript? - ProProfs

    Which Object Oriented Terms are Supported by Typescript?

    • Modulus

    • Interface

    • Classes

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    TypeScript supports all of the mentioned Object Oriented terms - Modulus, Interface, and Classes. Modulus is a mathematical operation and not directly related to Object Oriented programming. However, TypeScript supports Interfaces and Classes, which are essential components of Object Oriented programming. Therefore, the correct answer is "All of the above".

    ..... are the way to organise code in typescript. - ProProfs

    ..... are the way to organise code in typescript.

    • Modules

    • Classes

    • Method

    • Arrow

    Correct Answer
    A. Modules
    Explanation
    Modules are the way to organize code in TypeScript. They allow developers to split their code into separate files or modules, making it easier to manage and maintain. Modules help in encapsulating related functionality, promoting reusability, and providing better organization and structure to the codebase. By using modules, developers can import and export functions, classes, variables, and other entities, allowing them to create modular and maintainable applications.

    Which of the following is the typing principle of typescript? - ProProfs

    Which of the following is the typing principle of typescript?

    • Gradual

    • Dynamic

    • Duck

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The correct answer is "All of the above". This means that all three typing principles - Gradual, Dynamic, and Duck - are applicable in TypeScript. Gradual typing allows for both static and dynamic typing within the same codebase. Dynamic typing allows for variables to be assigned different data types at runtime. Duck typing allows for objects to be considered of the same type if they have the same set of properties. Therefore, TypeScript incorporates all these principles to provide a flexible and powerful typing system.

    Among which of the following computer programming language influenced the creation of typescript? - ProProfs

    Among which of the following computer programming language influenced the creation of typescript?

    • Java

    • JavaScript

    • C#

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the above computer programming languages influenced the creation of TypeScript. TypeScript is a superset of JavaScript, so it is directly influenced by JavaScript. It also draws inspiration from Java and C#, incorporating features from both languages. The goal of TypeScript is to provide a more structured and typed approach to JavaScript development, making it easier to build large-scale applications. Therefore, all three languages have played a significant role in shaping the design and functionality of TypeScript.

    The ...... Service powers the interactive TypeScript experience in Visual Studio, Vs Code, Sublime, the TypeScript playground and other editor. - ProProfs

    The ...... Service powers the interactive TypeScript experience in Visual Studio, Vs Code, Sublime, the TypeScript playground and other editor.

    • Typescript language

    • TypeScript compiler

    • Typescript main

    • TypeScript method

    Correct Answer
    A. Typescript language
    Explanation
    The TypeScript language powers the interactive TypeScript experience in various editors such as Visual Studio, Vs Code, Sublime, and the TypeScript playground. It provides the necessary tools and features for developers to write and edit TypeScript code efficiently. The language itself includes syntax, data types, and other language constructs that make it possible to write and execute TypeScript code in these editors.

    The following are backported features of typescript, except? - ProProfs

    The following are backported features of typescript, except?

    • Classes

    • Methods

    • Modules

    • Arrow

    Correct Answer
    A. Methods
    Explanation
    The given question asks for backported features of TypeScript, except for one option. The correct answer is "Methods." This means that all the other options (Classes, Modules, and Arrow) are backported features of TypeScript. A backported feature refers to a feature that is implemented in a newer version of a software or language but is made available in an older version. Therefore, in this case, methods are not a backported feature of TypeScript.
