JavaScript: Rotate the elements left of a given array of integers of length 3

JavaScript Basic: Exercise-70 with Solution

Write a JavaScript program to rotate the elements left in a given array of integers of length 3.

Visual Presentation:

Sample Solution:

JavaScript Code:

// Define a function named rotate_elements_left with a parameter array
function rotate_elements_left(array)
{
    // Return a new array with elements rotated to the left
    // The new order is [array[1], array[2], array[0]]
    return [array[1], array[2], array[0]];
}

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

Output:

[4,5,3]
[-1,2,0]
[6,5,7]

Live Demo:

See the Pen JavaScript - Rotate the elements left of a given array of integers of length 3 - basic-ex-70 by w3resource (@w3resource) on CodePen.

Flowchart:

ES6 Version:

// Define a function named rotate_elements_left with a parameter array using arrow function syntax
const rotate_elements_left = array => {
    // Use array destructuring to rearrange elements
    const [second, third, first] = array;
    // Return a new array with elements rearranged
    return [second, third, first];
};

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