Bosque (programming language) Developer Hiring Guide

Hiring Guide for Bosque (programming language) Engineers

Ask the right questions to secure the right Bosque (programming language) talent among an increasingly shrinking pool of talent.

Bosque is an experimental programming language developed by Microsoft. It was designed to improve productivity, reduce complexity, and enhance performance in cloud applications. Bosque uses a combination of functional, imperative, and object-oriented programming paradigms with a focus on algebraic operations and immutable data. The unique feature of Bosque is its ability to avoid accidental complexity in the development process by eliminating sources of programming errors like loops, conditionals or mutable state. Instead it promotes more predictable code execution through 'Structured Programming Constructs' that help reduce the cognitive load for developers when writing or reading code. Another key characteristic is its emphasis on automated reasoning tools which allows for advanced debugging techniques like symbolic testing as well as automatic documentation generation. This makes it easier to maintain large-scale software systems over time. While still in the experimental stage at Microsoft Research Labs, Bosque aims to provide new ways of thinking about program design which could potentially revolutionize how we write software systems in future.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Bosque (programming language).

What does this simple Bosque code do?

var x = 5;
var y = 10;
var z = x + y;
return z;

This code declares two variables x and y, assigns them the values 5 and 10 respectively, then adds them together and assigns the result to a new variable z. The code then returns the value of z, which is 15.

What will be the output of this Bosque code?

var str = 'Hello, Bosque!';
var res = str.split(', ');
return res;

This code splits the string 'Hello, Bosque!' into an array of strings at each occurrence of ', '. The resulting array ['Hello', 'Bosque!'] is then returned.

What does this Bosque code do with the array?

var arr = [1, 2, 3, 4, 5];
var sum = arr.reduce((a, b) => a + b);
return sum;

This code declares an array of numbers and then uses the reduce function to sum up all the numbers in the array. The result, which is 15, is then returned.

What does this Bosque code do related to threading?

var p = Promise.resolve(1);
p.then(v => v + 1).then(v => v * 2).then(v => return v);

This code creates a Promise that resolves to 1. It then chains three then calls, each of which transforms the value. The first adds 1, the second multiplies the result by 2. The final value, which is 4, is then returned.

What does this Bosque code do related to class design?

entity Point {
  field x: Int;
  field y: Int;
}
var p = Point@{x=1, y=2};
return p.x;

This code defines a class 'Point' with two integer fields 'x' and 'y'. It then creates an instance of 'Point' with 'x' as 1 and 'y' as 2. The code then returns the 'x' value of the 'Point' instance, which is 1.

What will be the output of this advanced Bosque code?

var arr = [1, 2, 3, 4, 5];
var res = arr.map(v => v * 2).filter(v => v > 5);
return res;

This code first maps over an array of numbers, multiplying each number by 2. It then filters out the numbers that are less than or equal to 5. The resulting array [6, 8, 10] is then returned.

How would you create a data structure in Bosque?

Data structures in Bosque can be created using the 'entity' keyword. For example, 'entity Point { x: Int, y: Int }' defines a Point with two integer fields.

What is the significance of 'None' in Bosque?

'None' in Bosque is used to represent the absence of a value. It is similar to 'null' in other languages, but is safer because it is a distinct type, not a value of every type.

How would you implement recursion in Bosque?

Recursion in Bosque can be implemented by having a function call itself within its body. Bosque supports tail-call optimization, which makes recursion more efficient.
