DRAKON-JS+++ is a computer programming language rooted in the DRAKON visual language developed by the Russian space program for clarity and simplicity. This software was designed to reduce human error in complex systems like spacecraft control algorithms. The JS+++ variant, specifically, implements this visual syntax into JavaScript, one of the most popular programming languages globally. It aims to enhance readability and comprehensibility while maintaining JavaScript's flexibility and wide-ranging functionality. As such, DRAKON-JS+++ offers an innovative approach that combines proven engineering principles with modern coding practices.

First 20 minutes

General DRAKON-JS+++ app knowledge and experience

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

How would you define DRAKON-JS+++?

DRAKON-JS+++ is a visual language and a software tool for the creation of source code in JavaScript. It is based on the DRAKON language which is designed to represent complex logic of programs in a more understandable way.

What are the main components of DRAKON-JS+++?

The main components of DRAKON-JS+++ are the DRAKON Editor and the DRAKON-JS runtime. The Editor is used to create and edit DRAKON diagrams, while the runtime is used to execute the diagrams.

Describe the difference between DRAKON-JS+++ and traditional JavaScript.

The main difference is that DRAKON-JS+++ uses a visual language for programming, while traditional JavaScript uses text-based coding. This makes DRAKON-JS+++ easier to understand and less prone to errors.

How would you create a DRAKON diagram in DRAKON-JS+++?

To create a DRAKON diagram, you would use the DRAKON Editor. You can add icons to the diagram by dragging and dropping them from the toolbox. You can also connect the icons by drawing lines between them.

What are the benefits of using DRAKON-JS+++ over traditional JavaScript?

The main benefits of using DRAKON-JS+++ are that it is easier to understand, less prone to errors, and more efficient in terms of development time. It also allows for better collaboration between team members as the code is more visually understandable.

Next 20 minutes

Specific DRAKON-JS+++ 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 execute a DRAKON diagram in DRAKON-JS+++?

To execute a DRAKON diagram, you would use the DRAKON-JS runtime. The runtime interprets the diagram and executes the corresponding JavaScript code.

Describe the difference between the DRAKON Editor and the DRAKON-JS runtime.

The DRAKON Editor is used to create and edit DRAKON diagrams, while the DRAKON-JS runtime is used to execute the diagrams. The Editor provides a visual interface for programming, while the runtime interprets the diagrams and executes the corresponding JavaScript code.

What are the limitations of DRAKON-JS+++?

One of the limitations of DRAKON-JS+++ is that it is not as widely used as traditional JavaScript, so there may be fewer resources and community support available. Also, while the visual language makes it easier to understand the logic of the program, it may be less flexible than text-based coding.

How would you debug a DRAKON diagram in DRAKON-JS+++?

To debug a DRAKON diagram, you would use the DRAKON-JS runtime's debugging features. You can step through the execution of the diagram, inspect the values of variables, and set breakpoints.

Describe the difference between DRAKON-JS+++ and other visual programming languages.

DRAKON-JS+++ is specifically designed for JavaScript and uses the DRAKON language, which is designed to represent complex logic in a more understandable way. Other visual programming languages may use different visual languages and may not be as focused on representing complex logic.

Oops! Something went wrong while submitting the form.

At this point, a skilled DRAKON-JS+++ engineer should demonstrate strong problem-solving abilities, proficiency in DRAKON-JS+++ programming language, and knowledge of software development methodologies. Red flags include lack of hands-on experience, inability to articulate complex concepts, or unfamiliarity with standard coding practices.

Digging deeper

Code questions

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

What does this simple DRAKON-JS+++ code do?
var x = 5;
var y = 10;
var z = x + y;
console.log(z);
This code declares two variables x and y, assigns them the values 5 and 10 respectively, adds them together to get a third variable z, and then logs the value of z to the console. The output will be 15.
What will be the output of this DRAKON-JS+++ code?
var x = '5';
var y = '10';
var z = x + y;
console.log(z);
This code will output '510'. Because x and y are strings, the '+' operator concatenates them instead of adding them numerically.
What does this DRAKON-JS+++ code do with the array?
var arr = [1, 2, 3, 4, 5];
arr.push(6);
console.log(arr);
This code declares an array with five elements, adds a sixth element to the end of the array using the push method, and then logs the updated array to the console. The output will be [1, 2, 3, 4, 5, 6].
What does this DRAKON-JS+++ code do related to threading?
setTimeout(function(){ console.log('Hello'); }, 3000);
This code sets a timer that waits for 3000 milliseconds (or 3 seconds), and then logs 'Hello' to the console. This demonstrates the asynchronous, non-blocking nature of JavaScript.

Wrap-up questions

Final candidate for DRAKON-JS+++ 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 DRAKON-JS+++ application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the best practices for using DRAKON-JS+++?

Some of the best practices for using DRAKON-JS+++ include keeping diagrams simple and readable, using meaningful names for icons and variables, and regularly testing and debugging the diagrams.

How would you integrate DRAKON-JS+++ with other JavaScript libraries?

You can integrate DRAKON-JS+++ with other JavaScript libraries by calling the library functions from the DRAKON diagrams. You would need to include the library in your project and then you can use its functions as you would in traditional JavaScript code.

Describe the difference between DRAKON-JS+++ and DRAKON-JS.

DRAKON-JS+++ is an enhanced version of DRAKON-JS. It includes additional features such as support for more JavaScript constructs, improved debugging capabilities, and better integration with other JavaScript libraries.
