JavaScript: Create a new array taking the middle elements of the two arrays of integer and each length 3

JavaScript Basic: Exercise-75 with Solution

Write a JavaScript program to create an array taking the middle elements of the two arrays of integer and each length 3.

The program extracts the middle elements from two arrays, each with a length of 3, and creates a new array containing these middle elements.

Visual Presentation:

Sample Solution:

JavaScript Code:

// Define a function named middle_elements that takes two arrays, 'a' and 'b', as parameters
function middle_elements(a, b) {
  // Create a new array named 'new_array'
  var new_array = [];

  // Push the second elements of both arrays into the new_array
  new_array.push(a[1], b[1]);

  // Return the new_array
  return new_array;
}

// Call the function with sample arguments and log the results to the console
console.log(middle_elements([1, 2, 3], [1, 5, 6]));    // Output: [2, 5]
console.log(middle_elements([3, 3, 3], [2, 8, 0]));    // Output: [3, 8]
console.log(middle_elements([4, 2, 7], [2, 4, 5]));    // Output: [2, 4] 

Output:

[2,5]
[3,8]
[2,4]

Flowchart:

ES6 Version:

// Define a function named middle_elements that takes two arrays (a and b) as parameters
const middle_elements = (a, b) => {
    // Create a new array and push the second element of each input array
    const new_array = [a[1], b[1]];

    // Return the new array
    return new_array;
};

// Call the function with sample arguments and log the results to the console
console.log(middle_elements([1, 2, 3], [1, 5, 6]));  // Output: [2, 5]
console.log(middle_elements([3, 3, 3], [2, 8, 0]));  // Output: [3, 8]
console.log(middle_elements([4, 2, 7], [2, 4, 5]));  // Output: [2, 4]
