These are the programming languages Google uses

Welcome back! When discovering which programming languages to learn, it maybe best to work backwards and find out which languages the top tech companies are using right now. Let’s take a look at Google and which programming languages they actually use!

First off

As always, if you have any suggestions, thoughts or just want to connect, feel free to contact / follow me on Twitter! Also, below is a link to some of my favorite resources for learning programming, Python, R, Data Science, etc.

Let’s begin!

The Languages

Let me go ahead and just tell you exactly what the languages are without wasting your time, i’ll explain them later. The languages that Google uses in house are: Javascript & Typescript for their front end, their backend is a little bit more complex: C, C++, Java, Python and Node. How do I know Google uses these languages? They’re on Wikipedia:

Now let’s go into detail for all of these languages:

Javascript & Typescript

Interestingly enough, almost all of the most popular websites use Javascript as their front end (with very few exceptions). Javascript is a dynamic object orientated language that essentially focuses on the front end, Typescript is actually a language created by Microsoft which is pretty much an updated version of Javascript. Both of these languages are extremely popular (obviously Javascript more so) and if you’re planning on becoming a programmer at any company, chances are you’ll probably run into Javascript or Typescript.

C / C++

C and C++ are both programming languages that Google uses, C is a fairly thorough language, the amount of things you can do with both C and C++ is insane, and it looks like both of these languages are highly used in Google. Now, C++ is an extension to the C programming language, C++ is actually commonly called “C with Classes”. Much like Javascript, i’ve seen C or C++ as a requirement for so many job descriptions it’s insane, so chances are if you learn C or C++, you will be helping yourself in the long run.


Go is actually a lesser known language, commonly known as Golang, this language was actually built by Google themselves. Based on what i’ve seen, it is commonly noted to be fairly similar to C, but there are a few notable differences. First off, Go has memory safety, garbage collection, structural typing and CSP-style concurrency, so even though it’s not as popular as C, there are still some massive reasons to learn this language since Google built it themselves.


This one is a no brainer, Java is a massively popular language that has tons of different uses. Java is commonly used to develop out mobile or desktop applications, programming out embedded systems or even handling many data processing tasks. This was actually one of the first programming languages I learned, although I don’t use it as much anymore, this is a very powerful language for sure.


Now this language I haven’t used before, just kidding! Python is one of the best programming languages i’ve ever used and it’s no surprise Google uses it as well. First off, we’ve seen Google develop tons of courses on learning Python since it’s a massive language they use. Although they probably use it for more than this, machine learning is a massive area that Google has invested in, they’ve created tons of machine learning frameworks within their package TensorFlow, so it’s no secret Python has a very large presence within Google.


Now technically Node isn’t really a language, it’s more of a framework from what i’ve seen. Essentially, Node (specifically Node.js) allows developers to run their Javascript code outside of a browser. I’m sure many projects utilize this in order to test out their Javascript code before pushing it to production.

There you have it! Hopefully this shed some light into your programming language journey, even though i’ve been programming for a while, it’s still extremely important to be learning other languages to become a well rounded engineer.
