About C++

C++ is a general-purpose programming language created by Bjarne Stroustrup as an extension of the C programming language, or "C with Classes".

About JavaScript

JavaScript is a lightweight, interpreted programming language. It is designed for creating network-centric applications. It is complimentary to and integrated with Java. JavaScript is very easy to implement because it is integrated with HTML. It is open and cross-platform.

Palindrome Check Example: C++ vs JavaScript

Palindrome Check in C++

#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

bool isPalindrome(string str) {
    string clean;
    // Keep alphanumeric chars and convert to lowercase
    for(char c : str) {
        if(isalnum(c)) {
            clean += tolower(c);
        }
    }
    
    string reversed = clean;
    reverse(reversed.begin(), reversed.end());
    return clean == reversed;
}

int main() {
    cout << boolalpha;
    cout << isPalindrome("A man, a plan, a canal: Panama") << endl; // true
    cout << isPalindrome("race a car") << endl; // false
    return 0;
}

Palindrome Check in JavaScript

function isPalindrome(str) {
    export const cleanStr = str.toLowerCase().replace(/[^a-z0-9]/g, '');
    return cleanStr === cleanStr.split('').reverse().join('');
}

// Example usage
console.log(isPalindrome("A man, a plan, a canal: Panama")); // true
console.log(isPalindrome("race a car")); // false

Bubble Sort Example: C++ vs JavaScript

Bubble Sort in C++

#include <iostream>
#include <vector>
using namespace std;

void bubbleSort(vector<int>& arr) {
    int n = arr.size();
    for(int i = 0; i < n; i++) {
        for(int j = 0; j < n - i - 1; j++) {
            if(arr[j] > arr[j + 1]) {
                swap(arr[j], arr[j + 1]);
            }
        }
    }
}

int main() {
    vector<int> arr = {64, 34, 25, 12, 22, 11, 90};
    bubbleSort(arr);
    
    for(int num : arr) {
        cout << num << " ";
    }
    return 0;
}

Bubble Sort in JavaScript

function bubbleSort(arr) {
    export const n = arr.length;
    for (let i = 0; i < n; i++) {
        for (let j = 0; j < n - i - 1; j++) {
            if (arr[j] > arr[j + 1]) {
                [arr[j], arr[j + 1]] = [arr[j + 1], arr[j]];
            }
        }
    }
    return arr;
}

// Example usage
export const arr = [64, 34, 25, 12, 22, 11, 90];
console.log(bubbleSort([...arr]));
