There is a string of programming languages that ruled the year 2020, they are Java, SQL, and JavaScript. But this will only be true if we consider only a few factors. Though there is a recent development in tech, we find it rather hard to adopt new programming languages. Big organizations prefer the old programming languages because they are cheaper and can easily adapt to any platform for their customers.

Java has always been the top programming language for a long time now. Though SQL and JavaScript are catching up developers still prefer Java. Its popularity is undefeated, hence its motto ‘write once, run anywhere

However, the world of tech is still evolving. Some new languages are here to stay. An example is Kotlin which was developed to replace Java. It surfaced in 2011 and gradually worked its way to the second official programming language in 6 years. Companies find it easy to move to Kotlin without messing their development process.           

On the other hand, young tech business owners prefer JavaScript due to profits, its flexibility, and adaptation to common trends.

SQL’s Popularity.

SQL is not as effective as Java because it is not a multipurpose language but it still has an increased demand among tech developers. It helps to effectively manage data while users gather new info. This makes it popular.

What is the reason behind this?

We have to find out the reasons for the popularity to get an accurate trend for 2021. The major factors include complexity and place of application. The complexity of programming languages makes it easy to learn and adapt to the language. These types of languages stay on the charts for a long time.

Though most programming languages are made to be multifunctional, their areas of application will determine their popularity. This contributes to the kind of supply their demands create. Most times, some prefer to make a new programming language like Rust than to adopt former ones. There is a surge of new programming languages in the tech industry amounting to about 300 programming languages out there.
