Every time you like a post, send an email on the computer, a programming language is working behind.

But where did it all begin? Let's take a tour of the history of programming languages.

🧵A Thread 🧵

1843: Machine Algorithm

Ada Lovelace invents the first-ever machine algorithm for Charles Babbage’s Difference Machine that lays the foundation for all programming languages.

1945: Plankalkül

In 1945, Konrad Zuse developed the first ‘real’ programming language called Plankalkül.

Zeus’s language allowed for the creations of procedures, which stored chunks of code that could be invoked over and over to perform routine operations.
