“Necessity is the mother of invention” – this saying has been the essence of human life evolution and thereby has resulted in continuous struggle of the human race to be more comfort-prone.
The world is becoming smarter day by day with the rapid development of Automation, Artificial Intelligence, Less manual intervention etc. This, in turn, is the result of continuous and tremendous efforts with the outcome of several technological advents and their intervention in the day-day activities.
As technology develops, the increase in the familiarity level of the programming languages also goes up drastically.
The list of programming languages that are in demand keeps changing depending on their usage, the number of performers/developers in that field and the continuous changes in that field.
However, the list of Top Programming Languages vary based on certain features:
a) Practical usage of languages in developing more user-friendly features/gadgets/applications.
b) The range and extent of their comfort levels in learning (say a new graduate or an experienced).
Even though some languages remain at the top of the programming languages list, some were not able to maintain their position.
However, a suggestion from an experienced developer/programmer or even a novice is perfect in whatever you are and how you try to adapt to the new trends and technologies which would be the stepping stones for your success as an individual.
Let's explore some of the top programming languages along with their features.

Top Most Popular Programming Languages in 2019
Enlisted below are the best and most used functional and object-oriented Programming Languages that you need to know in 2019.
Java continues to rock the top position in the charts of “Programming Languages”. Recently Java has completed its 22nd year since its advent in 1995 by James Gosling and the recent being Java11 on September 25, 2018.
The long run has been made possible by its features of platform-independence, scalability, security, etc. Java derives its features of object-orientation, variables, Data types of C/C++ and in fact, the syntax that is influenced by C++.
Java’s popularity is mainly due to its platform-independence feature which makes it run on different types of computer, either its Macintosh or Windows or Unix or Linux or even Mainframe/mobile phones as long as it has JVM installed in it.
Java code that has been written 15 years back can be made to run even on the latest JVM. One more notable feature is that it is fundamentally object-oriented and this makes Java be robust as Java objects contain no references to external data.

With speed, native code translating and memory management features, it continues to stay on top of the list with its newly ad-vented features.
The Class Library and Java API, which are a part of the Java Language, is the main learning of the Language. Even though Java consists of 50 Keywords, Java API has thousands of classes with tens of thousands of methods used in Programs.
Java is the learning language that is worth learning and it is the most preferable language to be learned by the developers.
Building server-based applications, web-applications, Android apps, Scientific applications, connecting to a Database, Internet of Things, Cloud development etc., are few to-do lists of things that you could do after learning this excellent language.
Open JDK, which is a free, open-source implementation, make it platform-independent across OS Environments.
Java is most commonly used in our daily life i.e. in most popular websites like Google, YouTube, LinkedIn, Amazon, eBay. Few other well-known/booming technologies like Android, Kotlin etc., are dependent on Java.
Python is an interpreted high-level programming language for general programming purposes. It was released in 1991.
Python has been designed to give importance to code readability and significantly using whitespaces. Dynamic type, automatic memory management, supporting multiple programming paradigm(PO, Functional, procedural), a large comprehensive library of its own etc., are its notable features.
Python interpreters are available for many operating systems and it is an open source software. As of January 2018, it is the fourth most popular language (after Java, c, c++). A recent study analyzed that such scripting languages are more productive than conventional languages.
Python can be embedded in many software products, used in several Artificial Intelligence projects & in the Information security industry and can also serve as a scripting language for web applications.
Large organizations that use python include Wikipedia, Google, Yahoo etc. Libre office includes python and intends to replace Java with python. Go, Kotlin, Swift etc, have derived some of their features from python.
With the growing trend of Hadoop ecosystem that is dependent on Python, Java, and Scala, Python provides an efficient competition to Java (as the world of analytics does not have many Java programmers),
Also, read Through our Free Python Tutorials for excellent knowledge of the language.
Swift is a general purpose, multi-paradigm, compiled programming that was developed by Apple Inc. for iOS, MacOS and for working with Cocoa frameworks. It uses the Objective C runtime library which allows C, C++ to run within one program.
Swift offers core concepts like dynamic dispatch, late binding, extensible programming, and address errors like null pointer de-referencing, supporting the protocol, extensibility, struts, classes etc. Swift won the first place for being the most Loved Programming language in 2015-2016.
Objective c which is a superset of C is used for creating OS and iOS applications.
Swift has entered as” Objective C without C”. The features of readability, maintenance, safer platform, less code, less legacy, speed, supporting dynamic libraries, interactive coding, open source, etc., make its an efficient choice for developing mobile projects.
Kotlin is a statically typed programming language that runs on JVM and can also be compiled to JS Source. It is fully supported by Google for the Android OS.
Kotlin is designed to be an OO language, that is fully interoperable with JavaCode. It also supports procedural programming with the use of its functions. Null pointer safety, extension functions, infix notation, full Java compatibility, and Good IDE support are some of the features that speed up the development process.
Kotlin library helps to build android UI applications. It has an interactive shell and can be used as an effective scripting language. Kotlin was officially announced as Android development language by Google. It is the third language that is fully supported for Android in addition to Java and C++.
C language is the oldest and most popular programming language. C is a general-purpose, imperative, computer programming language that supports structured programming. It was developed by Dennis Ritchie between 1969 and 1973.
It is designed to be compiled using a compiler, and provides low-level access to memory, offers an efficient mapping to machine instructions and requires minimal run-time support. Portability and capability of using in any embedded system are some of its outstanding features.
A portable assembly language that perfectly fits the operating systems along with a small run-time makes it a Universal Language.
C with Classes, the predecessor of C, C+++ was created by Bjarne Stroustrup in 1979. C++ is a general-purpose programming language. It has imperative, object-oriented and generic programming features.
Its design highlights include system programming, the flexibility of use, embedded resource constrained and performance efficiency with large systems.
C++ is a compiled language, that has its implementation available on many platforms. The other versions of programming languages like Java, C#, D etc., have been influenced by C++.
C with Classes added features to C compiler, includes classes, derived classes, strong typing, in-lining and default arguments. It was renamed to C++ by adding functions like virtual functions, operator-overloading, references, constants, type-safe, memory-allocation, improved type-checking, and a stand-alone compiler.
Its main components include direct mapping of hardware features and zero overhead abstractions based on those mappings. Though C++ is considered as a superset of C, it is strictly not true.
Even though it carries a similarity in its name with Java Language, it is distinct from Java by its dynamic functionality, human-readable code, etc.
The choice or preference of selecting a programming language varies from person to person depending on the requirements to be satisfied, the extent of availability of supported features/platforms, Individual capacity to learn and his/her interests.
Most importantly the average salary earned by implementing a specific programming language in his/her career domain will play a drastic role in choosing the right programming language.
