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

Create Array with Middle Elements from Two Arrays

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] 

For more Practice: Solve these Related Problems:

• Write a JavaScript program that extracts the middle element from two separate arrays (each of length 3) and returns a new array containing these two elements.
• Write a JavaScript function that accepts two arrays, validates their length, and creates a new array using the middle values from each.
• Write a JavaScript program that combines the central elements of two fixed-length arrays into a new array, handling edge cases appropriately.
