Tip

So many programing languages! You may be surprised by the very large number of prgramming languages that exist out there. What are the most popular? Why are there different languages?

1. Java

   • Portability: Java can run on nearly every system. Java is also the most popular Android language, so the vast majority of Android apps are built in Java.

   • Scalability: Java was built with scalability in mind

   • It has a large community

2. The C programming language

   • C is one of the oldest, most popular programming languages, thanks to its near universal portability and early adoption by Tech’s biggest brands

   • C is also the most popular language for embedded systems in cars, electronics, and other devices

3. Python

   • The popularity of Python has risen steadily over the past 15 years

   • Machine learning, artificial intelligence (AI), Big Data, and Robotics all rely heavily on Python

   • Python is very easy to learn and it is one of the most popular introductory language to learn!

4. Javascript

   • Web developers love JS as it allows them to add interactive effects to web pages.

   • It is simple and quite fast as well and many web apps are completely written in JS

5. Ruby

   • Ruby has an incredibly simple syntax that allows a developer to do more with less code.

   • Getting a web application up-and-running takes less time than in other frameworks.

   • However, a downside of Ruby is that is not scalable (that is: it has trouble handling large computing tasks even though it works great for smaller tasks)

10 most popular languages in 2019 and the change in popularity compared to the previous year. The rating is called The Tiobe Index: it works like market share; the percentage is the amount of “market share” a language holds, according to stackify.com.

Attention

Once you have completed this requirement, make sure you document it in your worksheet!
