Hiring guide for BeyondJS Engineers

BeyondJS Developer Hiring Guide

BeyondJS is not a recognized or established programming language. It's possible that there might be some confusion with the name. If you're referring to JavaScript, it is a high-level, interpreted programming language that conforms to the ECMAScript specification. JavaScript has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions. It's widely used for web development to make interactive elements on websites. If you're referring to Beyond.js as a specific library or framework within JavaScript (like Node.js or React.js), there doesn't seem to be any widely-known or commonly-used tool by that name in the current software development industry. Please provide more context if you mean something different by "BeyondJS".

First 20 minutes

General BeyondJS app knowledge and experience

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

How would you install BeyondJS?
You can install BeyondJS by using npm. The command is 'npm install beyond'.
What are the primary features of BeyondJS?
BeyondJS is a modular development framework. It has features like asynchronous module definition, server-side rendering, and real-time data binding.
How would you create a module in BeyondJS?
You can create a module in BeyondJS by using the 'module' function. You need to specify the module name and the dependencies.
What is the purpose of the 'beyond' command in BeyondJS?
The 'beyond' command is used to start the BeyondJS server. It serves the application and watches for changes in the code.
Describe the difference between 'require' and 'module' in BeyondJS.
'require' is used to import dependencies in a module, while 'module' is used to define a new module.

Next 20 minutes

Specific BeyondJS 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 errors in BeyondJS?
BeyondJS has a built-in error handling mechanism. You can use the 'catch' function to handle errors. You can also use 'finally' to execute code after a promise has been fulfilled or rejected.
What are the benefits of using BeyondJS over other JavaScript frameworks?
BeyondJS offers benefits like modular development, server-side rendering, and real-time data binding. It also has a powerful command line interface.
How would you implement server-side rendering in BeyondJS?
BeyondJS has built-in support for server-side rendering. You can use the 'render' function to render a module on the server side.
Describe the difference between synchronous and asynchronous module definition in BeyondJS.
Synchronous module definition blocks the execution of the code until the module is loaded, while asynchronous module definition allows the code to continue executing while the module is being loaded.
How would you implement real-time data binding in BeyondJS?
BeyondJS has built-in support for real-time data binding. You can use the 'bind' function to bind a model to a view. Any changes to the model will automatically update the view.

The ideal back-end app developer

What you’re looking to see on the BeyondJS engineer at this point.

At this point, a skilled BeyondJS engineer should demonstrate strong problem-solving abilities, proficiency in BeyondJS 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 BeyondJS.

What does the following simple BeyondJS code do?
const express = require('express');
const app = express();
app.get('/', function (req, res) {
  res.send('Hello World!');
app.listen(3000, function () {
  console.log('Example app listening on port 3000!');
This code creates a simple Express.js server that listens on port 3000 and responds with 'Hello World!' when the root ('/') URL is accessed.
What will be the output of the following BeyondJS code snippet?
let x = 10;
function foo() {
  let x = 20;
The output will be '20' and then '10'. This is because the 'x' inside the function 'foo' is a different variable (due to the 'let' keyword) than the 'x' outside the function.
What does the following BeyondJS code do?
let arr = [1, 2, 3, 4, 5];
let sum = arr.reduce((a, b) => a + b, 0);
This code calculates the sum of all elements in the array 'arr'. The 'reduce' function is used to accumulate a result by applying a function (in this case, addition) to each element of the array.
What does the following BeyondJS code do?
const promise1 = new Promise((resolve, reject) => {
  setTimeout(resolve, 500, 'one');
const promise2 = new Promise((resolve, reject) => {
  setTimeout(resolve, 100, 'two');
Promise.race([promise1, promise2]).then((value) => {
This code creates two promises that resolve after different amounts of time. The 'Promise.race' function is used to create a promise that resolves or rejects as soon as one of the promises in the iterable resolves or rejects. In this case, 'two' will be logged to the console because 'promise2' resolves first.

Wrap-up questions

Final candidate for BeyondJS 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 BeyondJS application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the limitations of BeyondJS?
BeyondJS is a relatively new framework, so it may lack some features and have fewer resources available compared to more established frameworks. It also requires a good understanding of JavaScript and modular development.
How would you optimize the performance of a BeyondJS application?
You can optimize the performance of a BeyondJS application by using techniques like lazy loading of modules, optimizing server-side rendering, and minimizing the number of real-time data bindings.
Describe the difference between BeyondJS and Node.js.
BeyondJS is a modular development framework, while Node.js is a runtime environment for executing JavaScript code. BeyondJS can be used with Node.js to build scalable web applications.
