Welcome back! Facebook is a massive social media website that employs tons of people, so, let’s take a look at some of the programming languages that this company uses!

Let’s take a look at some of these languages!

C and C++

First up, C and C++ are very popular languages that i’m sure everyone knows about. C is one of those languages that whatever software engineering position (even some data science positions) are going to require it regardless. C++ is another very popular language, this language was originally known as “c with classes”. Since it’s origination, it’s pretty much been it’s own language. You can build out a lot of different things with both C and C++: Games, Applications, Operating Systems, etc..

Python
