1. Python

Because of such a lucid syntax, Python has become every developer’s favorite programming language. Python is loaded with myriads of tools and a vast library to assist the developer. In addition to that, it’s interoperability with parent object-oriented programming languages such as C and C++ is noteworthy. This is the reason why Python is preferred by new as well as experienced developers.

2. Java programming language

Java is one of the most popular programming languages in use, so it’s no surprise it came in as the No. 1 skill tech companies were looking for. According to Oracle, 3 billion mobile phones run Java, along with 125 million TV devices and 89% of desktop computers in the U.S. Java is everywhere and the demand for strong developers is high. In the US, a Java developer makes a median salary of $85,000. There are many job postings for Java developers and Java engineers, but if you want to be a software developer or engineer of any kind, knowing this coding language is typically a core requirement.

3. Kotlin

This iconic future programming language is all set to replace Java. Yes, you read that right! Kotlin is a cutting-edge language that is also multi-dimensional, practical, and popular, making it the most preferred language for Android app developers.

4. SQL programming language

Pronounced “sequel,” SQL stands for Structured Query Language, and it is a special-purpose language used for getting information from and updating databases. Since nearly all businesses run a database system of some kind, SQL is a good skill to have on your resume. It’s also one of the easier tech skills to learn, with numerous tutorials and free resources online (we like this one that lets you learn the language while blowing up spaceships). If you become an expert, you could be a candidate for jobs like SQL database manager, SQL developer, and SQL Analyst—but a lot of general data analyst jobs will also require you to know SQL, as it’s widely used across database applications and web frameworks.

5. Swift

Swift is a compiled, general-purpose, multi-paradigm object-oriented programming languages that Apple created as an upgrade to Objective-C. It is a fun and expressive scripting language that lets you play around with the code and see what happens in real time. 

6. SQL programming language

7. R

Software engineers use R to process statistics, compute, test, visualize, and analyze. You only need a good understanding of math's to start working on this language. Like Python, R comes with a large number of libraries, such as ggplot, tidyr, leaflet, and more. Thus, the R programming language works with statistics and analyzes data. Since it is a object-oriented programming languages, it can be used to write code to do things automatically. 

8. Javascript programming language

Javascript is a scripting language, often used to make web pages interactive. It’s text-based, written in an HTML document, and runs through a web browser. There are plenty of jobs out there for JavaScript developers. Anyone looking for a job as a front-end web developer (the person who does the coding for the part of the website you actually see, as opposed to the database or servers) will also need to know Javascript, in addition to HTML, CSS, and other scripting languages. Java is nothing but the progenitor of Javascript.

9. TypeScript

TypeScript is a documented OOP language that adds types to JavaScript to make it more powerful. However, it lets you build large applications with a syntax that is easy to understand and has few mistakes. Moreover, it is becoming very popular among developers because it makes JavaScript code simpler, which makes it easier to read and fix bugs. Also, it has a lot of tools for developing JavaScript IDEs and practices. Well, if you know what JavaScript and OOP are and how they work, the TypeScript tutorial will be easy to understand. Thus, it is a typed version of JavaScript that makes plain JavaScript when compiled. In other words, it is fully object-oriented, with interfaces, classes, and static typing, just like Java or C#.

10. C++ programming language

C++ is a general-purpose programming language that can be used to create small programs or large applications. As an extension of C, one of the oldest coding languages, C++ for game development provides a foundation for many newer, more popular ones. There are plenty of C++ developer job postings, and it’s basically assumed that a candidate for nearly all software engineer or developer jobs will have some experience with the language. It is noteworthy that almost all major Adobe applications are developed in C++ for game development.
