WhatsApp is a wildly popular messaging service used by billions of people around the world. It provides users with an easy, reliable way to communicate with friends, family and colleagues via text, voice calls and video calls. As such, it has become an integral part of many people’s lives.
But what programming language is used to make WhatsApp? The answer is a combination of several languages. Chief among them are Erlang, a programming language developed by Ericsson in the late 1980s; and Java, a popular programming language created by Sun Microsystems in 1995.
Erlang is the primary language used by WhatsApp’s backend servers. It’s known for being highly fault-tolerant and reliable, allowing WhatsApp to handle billions of messages without fail. Erlang also makes it easy to scale up or down depending on the number of users connected to the platform at any given time.
Java is used for building the client-side applications that run on Android and iOS mobile devices. Java is known for its portability and flexibility, making it easy for developers to create apps that work across different types of hardware and software platforms.
Other languages, such as C++ and Objective-C are also used for specific parts of the app’s codebase. For example, C++ is used for low-level tasks like memory management while Objective-C is used for MacOS development.
In conclusion, WhatsApp uses a combination of Erlang and Java as its main programming languages. Other languages such as C++ and Objective-C are also employed in certain areas of development.
Conclusion:
WhatsApp uses a combination of Erlang and Java as its main programming languages with smaller amounts of C++ and Objective-C being employed in certain areas. These languages have been carefully chosen due to their respective benefits which allow WhatsApp to offer its users an efficient messaging experience.
