Which programming language are best for getting a job? Python is the best programming language for getting a job. Since the TIOBE Index reports Python as being the most popular programming language in the world, that means there is a reasonably high demand for professionals with Python programming skills.
What is a programming language?
Programming languages are what software developers use to communicate objectives to and between computers. There's a suite of existing languages these professionals use to program applications, scripts, queries and more.
7 best programming languages to learn
There are a variety of programming languages you can learn that are currently in high demand from employers. Learning one or more of these programming languages may help you qualify for high-salary opportunities and may make you a versatile candidate for several positions.
1. C/C++
C is a low-level language, meaning that programming in it requires knowledge of the underlying computer hardware. While this makes other languages much easier to learn, it comes at the cost of performance. This might not have much impact on a social media app, but it's extremely important in applications such as games, movie special effects software and even portions of operating systems like Microsoft Windows or Linux. It's also vital on the other end of the computing spectrum. Embedded devices such as car computers have limited computational power and need to get the most out of it.
Designers derived C++ from C to simplify its programming, and they still classify it as a low-level language. C is somewhat of a subset of C++, meaning that professionals can translate C programs to C++ with relative ease. However, C++ is much more attuned to application development, while organizations leverage C in embedded systems or key sections of applications. While high-level languages come in and out of popularity and use because of being removed from the hardware, C and C++ have maintained relevance and usefulness over time.
2. Java
Java is a popular language for web application back-ends or general service application programming interfaces (APIs) enabled by frameworks such as Spring and Dropwizard. Though Java has a similar name to JavaScript, the languages have very little in common. Unlike JavaScript, Java is a strongly typed language, a feature that can mean a steeper learning curve. However, the trade-in complexity offers much higher performance, particularly with the ability to multi-thread work or break work up into smaller tasks that can run simultaneously. JavaScript, however, only uses a single thread.
Its balance of performance and complexity makes Java a great option for web application back-ends, particularly when heavy data manipulation or math is required. For those aspiring to create mobile apps, professionals use Java to create applications for Android.
3. JavaScript
Website interactivity and richness have dramatically increased in recent years. HTML and CSS are the foundation for existing technological systems, but the driver of these user interfaces is JavaScript. Programming in JavaScript has become easier with industry-standard tools such as the powerful, beginner-friendly VueJS or the more advanced ReactJS and Angular, formerly AngularJS.
4. Python
Python is a popular coding language that uses clean code that's easy to read and write. Its versatility makes it an effective tool for projects ranging from web application development to video games. More recently, it has seen growing popularity in the fields of data science and machine learning. This is due to scientific tools such as Pandas, NumPy
5. SQL
Unlike the other languages on this list that help professionals write programs, SQL-“Structured Query Language” and often pronounced “sequel”-is for querying data. Programmers submit SQL data queries to a server that then returns the requested information. While standardized, there are many variants such as PostgreSQL and Microsoft's SQL Server. Since they're similar, learning one variant makes it significantly easier to learn about others.
6. Swift
Swift is the language exclusive to the Apple ecosystem of products, including the iPhone and iPad. The original language Apple used was its own C-inspired language, Objective-C. In 2014, developers introduced Swift to lower the development barrier to entry for the platform with a modern language that's significantly easier to learn.
7. TypeScript
Unlike the other languages on this list, TypeScript is a language that converts to another language: JavaScript.
On the left, you see a TypeScript function, and on the right is the resulting JavaScript. The only change made when the code translated-or transpiled-to JavaScript was the removal of the “number” annotation.
