Jove is a computer programming language developed by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in the 1960s. It was one of the first widely used interactive programming languages, and was used to teach introductory programming courses at many universities. Jove is a descendant of BASIC, and is similar to ALGOL 60. It was originally implemented on a GE-225 computer, and later ported to a variety of other platforms. The Jove programming language is no longer in active development, but it is still used by some universities for teaching introductory programming.

First 20 minutes

General Jove app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Jove application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you describe the basic structure of a Jove program?

A Jove program is structured around the concept of 'objects'. It consists of a series of definitions and commands. Definitions include object definitions, function definitions, and variable definitions. Commands include function calls and assignments.

What are the basic data types in Jove?

Jove supports several basic data types including integers, floating-point numbers, strings, and booleans.

How would you declare a variable in Jove?

In Jove, you can declare a variable using the 'var' keyword followed by the variable name and its value. For example, 'var x = 10;' declares a variable named 'x' with the value '10'.

Describe the difference between a function and a method in Jove.

In Jove, a function is a standalone procedure that performs a specific task, while a method is a function that is associated with an object and can access and modify the object's properties.

What are the control flow structures in Jove?

Jove supports several control flow structures including 'if' statements, 'for' loops, 'while' loops, and 'switch' statements.

Next 20 minutes

Specific Jove development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

How would you handle exceptions in Jove?

In Jove, you can handle exceptions using the 'try-catch' statement. The 'try' block contains the code that may throw an exception, and the 'catch' block contains the code that will be executed if an exception is thrown.

What are the different ways to create an object in Jove?

In Jove, you can create an object using the 'new' keyword followed by the object constructor, or you can create an object literal by enclosing a list of properties and values in curly braces.

Describe the difference between '==' and '===' in Jove.

In Jove, '==' is the equality operator that compares the values of two operands and returns true if they are equal. '===' is the strict equality operator that also checks the type of the operands and returns true only if both the value and the type are equal.

How would you implement inheritance in Jove?

In Jove, you can implement inheritance using the 'extends' keyword. You can create a subclass that inherits the properties and methods of a superclass by declaring the subclass with the 'extends' keyword followed by the superclass name.

What are closures in Jove and how would you use them?

In Jove, a closure is a function that has access to its own scope, the outer function's scope, and the global scope. You can use closures to create private variables and methods, to implement data hiding and encapsulation, and to create function factories.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Jove.

What does the following simple Java code do?
public class HelloWorld {
 public static void main(String[] args) {
 System.out.println("Hello, World!");
 }
}
This code prints 'Hello, World!' to the standard output.
What does the following Java code do?
public class Test {
 public static void main(String[] args) {
 int x = 10;
 int y = ++x;
 System.out.println(y);
 }
}
This code increments the value of 'x' by 1 before assigning it to 'y'. So, 'y' will be 11.
What does the following Java code do?
import java.util.Arrays;
 public class Test {
 public static void main(String[] args) {
 int[] arr = {1, 2, 3, 4, 5};
 Arrays.sort(arr);
 System.out.println(Arrays.toString(arr));
 }
}
This code sorts the array 'arr' in ascending order and prints the sorted array.
What does the following Java code do?
public class Test {
 public static void main(String[] args) {
 Thread t = new Thread(() -> {
 System.out.println("Hello, World!");
 });
 t.start();
 }
}
This code creates a new thread that prints 'Hello, World!' to the standard output when it's started.

Wrap-up questions

Final candidate for Jove Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle Jove application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

Describe the difference between 'null' and 'undefined' in Jove.

In Jove, 'null' is a special value that represents no value or no object. 'undefined' means that a variable has been declared but has not yet been assigned a value.

How would you handle asynchronous operations in Jove?

In Jove, you can handle asynchronous operations using callbacks, promises, or async/await. Callbacks are functions that are passed as arguments to another function and are invoked when the operation is completed. Promises represent the eventual completion or failure of an asynchronous operation. Async/await is a syntactic sugar over promises that makes asynchronous code look and behave like synchronous code.

What are the different ways to import a module in Jove?

In Jove, you can import a module using the 'require' function or the 'import' statement. The 'require' function is used in CommonJS modules, while the 'import' statement is used in ES6 modules.
