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.

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]
