What makes a good programming language? Ask three developers, and you will get five different answers. So, let’s keep it simple and take a closer look at the “good” first. We will go by popularity: which programming languages are most commonly used by developers?
In their 2020 Developer Survey, StackOverflow asked more than 65,000 developers what the most commonly used programming languages are. Here are the results:
The third most commonly used programming language is SQL or Structured Query Language. SQL is an all-time favourite. It made its first appearance in 1974, and thus predates the internet by a few decades. It is easy to learn and lets you interact with a database. For example, say you create a web application on top of a MySQL database. In order to write queries, you would need to use SQL. Relational databases are extremely popular ways of storing data. Based on a survey by popular online community of data scientists Kaggle, SQL databases are the most commonly used databases by data scientists. Large websites like Uber, Airbnb or Netflix also use MySQL, an open source version of a relational database, as part of their tech stack.
