What is the programming language used in WhatsApp?


ERLANG language: is the programming language used in coding the WhatsApp application, where a code restructuring and some important changes were made to the (Ejabberd) server to achieve optimal server performance.


WhatsApp uses the Ejabberd XMPP server that facilitates the transmission of instant messages between two or more users in real-time. Erlang) has the flexibility to adapt to instant updates and quick fixes, which helps WhatsApp push changes quickly into direct execution without the need for a reboot.


How was the WhatsApp application developed?


The idea of instant messaging first began in 1961 when the Computing Center at the Massachusetts Institute of Technology created the Compatibility Time-Sharing System (CTSS). Surprisingly, this new system was such an absolute success that by 1965. hundreds of MIT and University of New England students were already registered users.


1. Insights about WhatsApp data transfer:


The WhatsApp application technically manages more than 50 billion messages per day, where the key to smooth data processing lies in the length of the message queue. HTTP) and associate it with the content and then send it to the receiving point in the form of a thumbnail, depending on the user's preference the content can either be viewed or ignored.


2. The protocol used by WhatsApp:


The primary protocol used is Extensible Messaging and Presence Protocol (XMPP), where DSL ensures network security and also helps prevent private data transmission. When a message is delivered, the sender is notified with a double checkmark near the message, and after delivery, the messages are immediately deleted from the server's memory.

This instant deletion of server memory helps WhatsApp keep its resources to a minimum, in addition, WhatsApp uses HTML5 WebSockets, a communication technology that facilitates two-way communication.


3. The process of registering in the WhatsApp application:


Users can register in the WhatsApp application by entering their mobile phone number, and when entering the number, a one-time password will be sent to the user, which once verified by the device will start the user on the chat screen.


4. Managing the database in WhatsApp:


Mnesia DB handles the heavy-duty database management task as Mnesia is a multi-user distributed DBMS that is the default database for ERLANG and helps Mnesia achieve faster responses to requests and thus improve overall efficiency.


As for FreeBSD, it is the operating system on which the WhatsApp application is built, by improving the applications based on (ERLANG) and improving (FreeBSD). Where the WhatsApp application can achieve better performance, in order to store multimedia files as the application uses an exclusive web server (YAWS).


5. End-to-end encryption in WhatsApp:


The end-to-end encryption of the WhatsApp application ensures solidity to ensure the security of text and multimedia content, and when sending messages, your phone performs encryption and sends it to the WhatsApp server where the server gets the responses from the recipient’s end, encrypts them, and sends them to your smartphone, and your phone decrypts and displays the messages.


6. WhatsApp Voice and Video Calls:


WhatsApp uses high-processing advanced technology instead of (WebRTC) audio codec (Opus / SILK) around (16 kHz at a bit rate of 20 kbps) and Network Address Translation (NAT) technologies to enable voice communication. STUN) and peer-to-peer communication is an essential element that is included to enhance and maintain authentication for users.


7. Share location on WhatsApp:


It integrates (WhatsApp API) for (Google Android) Maps and (Google Places API) where this API is used to share the location between users, and the WhatsApp application is also optimized according to their multiple needs.


8. WhatsApp Payment Module:


  • UPI: The Unified Payment Interface (UPI) is one of the most secure, easy-to-use payment modules that allows instant payments.
  • Address (VPA): The default payment address will use the email address registered to the particular bank account which can be shared publicly instead of the bank account number and IFSC code.
  • MPIN: Mobile Banking Personal Identification Number (MPIN) is a 4-6 digit security code used to authenticate all types of UPI funds.
