So Facebook is using Hack, Java, C++, Erlang, Python, Haskell, Dlang and PHP in the back-end.įacebook only uses one language in the Front-end that is JavaScript. Facebook uses PHP for web content management.
PHP: PHP is one of the most popular programming languages for server-side web development. It is not a popular programming language, but it is a powerful language for GPU programming, operating system kernel, virtual machines, and text processing. Dlang: Dlang or D is used in companies like Facebook, eBay, and Netflix. Facebook uses Haskell to implement its anti-spam programs. Haskell: Haskell is a general-purpose, functional programming language used in Facebook in the back end. It is widely used in Facebook in back-end development and machine learning. Python: Python is one of the most popular programming languages. #Miana head of programming for facebook programing code
It is not a popular programming language today but is used in distributed, fault-tolerant, highly available applications where code can be changed any time without stopping the application. Erlang: Erlang is a general-purpose, functional programming language used by Facebook in the back end.

Facebook also uses C++ at the back-end because of its popularity among software engineers. I prefer C++ for all the problems other than Data Science and Machine Learning.
C++: C++ is one of the fastest programming languages I have used. The Hack programming language is not that common among programmers, but as Facebook has created it, so it uses Hack in the back end. Hack: Hack is a programming language created by Facebook as a dialect of PHP. Since it is so popular among computer science students and software engineers, it is used by Facebook in the Back-end. It is one of the programming languages that is the first programming language for computer science students. Java: You must have heard a lot about Java. So let’s start by going through all the programming languages used by Facebook at the Back-end: Most of the programming languages that Facebook uses at the back-end are very popular in the coding community. It has a bit of a "No True Scotsman" thing going for it.īut as a heuristic think maybe about when you'd use patern matching to destructure something vs say a nested set of if and elses.There are a lot of programming languages that Facebook is using at the Back-end. The point I think is, it is just as technical as "functional" is. > What (technical!) definition “declarative” are you using? As opposed to say sticking it in a large object instance in a global singleton and then everything calls 100 something methods to mutate it. Minimizing means making it explicit, passing it around, using immutable data. > Functional programs have plenty of state - which changes over time. Is that a translation from another langauge or a functional programming terminology? I went to the standard 4 year CS program. IME trees, graphs and array problems are the most asked. Pretty weird that DP is so relevant in leetcode but not in interviews. But Elixir has mutable variable, while Erlang doesn't.Īs for assignables, I've never heard that word. I interviewed at many many well known places and the ONLY company who asked a DP problem was Bloomberg. For example both Erlang and Elixir have immutable data. Then I can see how they'd be very confused by that statement. Unless someone did strictly functional programming and math. Like it or not that is the bread and butter of programming. What imperative languages have is “assignables”. > Variables don't “mutate”, they are substituted with other expressions. Without tail call elimination recursion will blow the stack. Because of lack immutability, recursion is used. Well Erlang is not strict and has tail call elimination. > Tail call elimination is just the right way to implement tail calls in a strict language. You can't create the most performant data structures possible if all your operations require path copying, but mutability should be reserved for internal high performance library creation and avoided in business logic/application level code to make systems easier to reason about.Įxcept when they are not there done properly (cough cough Python), it not so fun doing functional programming. your program would just heat up the computer, which, in a way, is its own form of output, so you can't ever be fully functional).Įvery functional language gets non-functional at some point for data processing, bootstrapping, loading/saving programs, and the best functional languages even have optional mutability constructs for performance (see: !). You just create functions and cons cells and the rest of the world gets built on top of those.īut, pure functional systems are useless (to be purely functional would mean you can't even do I/O. Some flavors actually have (practically) zero mutability. 
You run an implementation of Lisp allowing various operations. Completely wrong but delivered with strong convictions.
