If you are a beginner in the IT field, the first question that comes to your mind is: From where should i start ? There are hundreds of fields to choose from for example you can choose the ones based on your career goals.
One of the easiest way to choose the suitable programming language to learn is to see where the tech trend is heading to.
In this day I'll list the 10 most demanded programming languages in the market so let's proceed

1-JavaScript:

JavaScript (JS) was crafted in 1995 at Netscape as LiveScript. JavaScript is interpreted and run by a JavaScript engine. JavaScript is the programming language of HTML and the Web.JavaScript is easy to learn very expressive and very little setup overhead (just open your browser and start coding). These days, JavaScript is used for both client-side and server-side web development, as well as in desktop application development, drones, Internet of Things (IoT), and other things.
If you are a beginner programmer, then just learn JavaScript and you won’t need to learn any other languages.

2-Python:

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics.Created by Guido van Rossum and first released in 1991,Python’s combination of simplicity and power makes it an ideal choice as a place to start. It enables you to implement the functionality you want without any hassle and lets you write programs that are clear and readable. Python is used extensively for system administration tasks,also used in web development,software development, scientific and numeric.Python is a good choice to start with for a beginner.

3-Java:

Java is currently one of the most influential programming languages created in 1995 by sun and then owned by Oracle, is a general purpose programming language. It has features to support programming based on the object-oriented, procedural, and functional paradigms. Java became a very popular programming language. One of the most important features for its popularity was its “write once, run anywhere” (WORA) feature. This feature lets you write a Java program once and run it on any platform. It has so many characteristics such as simplicity,wide variety of usage environments, robustness. Java is most used in mobile applications (specially Android apps), desktop applications, web applications, web servers and application servers.

4-C and C++:

C is a procedural programming language while C++ is a general-purpose programming language the former was created in 1972 and the latter in 1983 which makes them one of the most old programming languages. C is a widely used language and was used to write the early versions of Unix and Windows as I aforementioned earlier C does not support OOP and clearly there was a need for the power of C but the flexibility and extensibility of object-oriented classes: a language that was C, with classes.So C++ was released to accomplish this task. Those two languages are mostly used in game development, virtual reality, and computer graphics

5-PHP:

PHP is a mature, powerful language that’s become the most widely used technology for creating dynamic web sites it is a general-purpose programming language.PHP started out in 1995. It’s free and has a very gentle learning curve it’s platform-neutral, that means the same code runs on Windows, macOS, and Linux. Now the latest stable release is PHP 7. PHP is the language that drives highly popular frameworks and content management systems such as Laravel, Drupal, and WordPress. As mentioned earlier it is used for web development.

6-Swift:

Swift is a general-purpose, multi-paradigm, compiled programming language. This is a brand new programming language, developed by Apple and announced in 2014 and make it work seamlessly with the existing Objective-C language. In 2016, Swift 3 was released as open source, and this is the first major version,now the latest version is Swift 5. it helps you to write without hassle. Swift draws upon an extensive history of language design and has a number of very cool design features that make developing software easier, simpler, and safer. This latter is used to develop iOS apps, Mac OS apps,watchOS.

7-C sharp(C#):

C# is a general-purpose too It was developed around 2000 by Microsoft as part of its .NET initiative,it's easier to learn compared to other languages such as C++, its uses the Visual studio as its IDE . C# is a widely used programming language, thanks to its easy learning curve, versatility, and support for modern paradigms. It is used to create desktop apps, background services, web apps, and mobile apps. Also, the .NET Core is open sourced and is compatible with Mac OS and Linux apart from Windows. Thus, there is no limit to what you can achieve with C# and .NET Core.

8-Objective-C:

Objective-C is a general-purpose programming language was developed in 1984 by Apple and it is considered the primary programming language used when writing software for OS X and iOS and their respective application programming interfaces (APIs) Cocoa and Cocoa Touch.

9-Kotlin:

Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference created by Jet brains in 2011. Kotlin is typically associated with Android development, and most discussions surrounding it gravitate around this. However, the language has much more to offer and is ideal for modern server-side developers. On 7 May 2019, Google announced that the Kotlin programming language is now its preferred language for Android app developers.

10-SQL:

SQL (pronounced "ess-que-el") is a domain-specific language used in programming and designed for managing data held in a relational database management system. SQL statements are used to perform tasks such as update data on a database, or retrieve data from a database.SQL is mostly used in database applications and the WEB.

Conclusion:

To determine nowadays what programming language to choose is very hard because software industry is in a constant development. So it's only you who can decide which language that is suitable for your needs
