Digging deeper

Code questions

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

What does the following Biferno code do?

var a = 10;
var b = 20;
var c = a + b;
return c;

This code declares two variables a and b, assigns them the values 10 and 20 respectively, then adds them together and assigns the result to a third variable c. The value of c, which is 30, is then returned.

What will be the output of the following Biferno code?

var str = 'Hello, World!';
var res = str.substring(7, 12);
return res;

This code declares a string variable str and assigns it the value 'Hello, World!'. It then uses the substring method to extract a portion of the string from index 7 to 12. The result, which is 'World', is then returned.

What does the following Biferno code do?

var arr = [1, 2, 3, 4, 5];
var sum = 0;
for (var i = 0; i < arr.length; i++) {
  sum += arr[i];
}
return sum;

This code declares an array arr and a variable sum. It then uses a for loop to iterate over the array and add each element to sum. The final sum of all the elements in the array, which is 15, is then returned.

What does the following Biferno code do?

var a = 10;
var b = 20;
var c = a + b;
return c;

This code declares two variables a and b, assigns them the values 10 and 20 respectively, then adds them together and assigns the result to a third variable c. The value of c, which is 30, is then returned.

class Person {
  var name;
  var age;
  function Person(n, a) {
    this.name = n;
    this.age = a;
  }
}
var p = new Person('John', 30);
return p;

This code defines a class Person with two properties: name and age. It also defines a constructor for the class that takes two parameters and assigns them to the name and age properties. It then creates a new instance of Person with the name 'John' and age 30, and returns this instance.

What will be the output of the following Biferno code?

var a = 10;
var b = function() {
