Top 5 Best Programming Languages to learn in 2020.

Today, software engineering and developing has extended in every industry.  Many programming languages are developed that are appropriate for different levels from junior to specialist. If you’re trying to advance in your career entirely, and you realize you need to master a programming language, you might wonder which one to learn and you want to make the right choice from the start.

In writing this article, we have consulted the specialists, our Colibri team of developers and are happy to share some of their suggestions of the top 5 programming languages of 2020. Don’t worry we have also done our research to back these suggestions up with data from different sources on market demand, product trends, career-prospects, learning resources and so forth. Even a programming language described as appropriate for a beginner does get more complicated as you become more proficient and experienced in using it.

1. Python

Based on the PYPL index for February 2020, as we can see, Python is the top language learning at the moment followed by the other languages.

First, python is a user-friendly language. Because of its simple and powerful syntax, it is considered the easiest language to learn and is used to teach programming. Widely used for ML, DL and computing science. Python facilitates streamlining the development of web and mobile applications.

Job Market:

• Python offers a path to finding meaningful work. While some of that potential work seems obvious such as becoming a Python developer. According to Indeed, there are more than 1,885 jobs posting currently in Vietnam, Python is the most demanding programming language in the USA job market with the 61,000 job postings in 2020.

• Python developers earn high salaries with relatively low experience compared to other mainstream programming languages.

• If you are an experienced Python, you might want to advance in Python to brush up your skills. We suggest some of the useful books to helps you master this version of the language such as Python Cookbook; Programming Python etc.

For beginners, leveraging Python skills into a tech job or software developer positions are a great place to start. leveraging Python skills into a tech job or software developer positions are a great place to start. Job Duties of entry-level software developers include: Assisting with writing, editing, and maintaining software programs Testing code—running programs (often controlled with Python scripts) to test code for errors, Debugging code—analyzing code errors and fixing them and tracking version changes and logging errors.

Pythonguru, Learnpython and Codecademy is some of the tutor focused on beginner programmers as well as experienced programmers. It covers many Python concepts in depth. It also teaches you some advanced constructs of Python like lambda expressions and regular expressions.

2. Java

Java is one of the most disruptive programming languages to date. It has achieved Platform independence by developing Java Virtual Machine (JVM). One plus point is that Java programs should be able to run on a network, no matter what operating system they're running.

In recent years, Java has lost some of its markets to highly developer-friendly modern languages and the rise of other languages, especially Python, JavaScript. Also, JVM is not quite Cloud friendly because of its bulky size.

Java is still the number one programming language for enterprises.

Key Features:

• Java offers a powerful, feature-rich, multi-paradigm, interpreted programming language with a moderate learning curve and high developer productivity.

• Java is strictly backward compatible, which is a crucial requirement for business applications.

• Java’s runtime JVM is a masterpiece of Software Engineering and one of the best virtual machines in the industry.

• Virtually any business today needs an Android App due to today's high Android user demand. This opens up a great opportunity for Java developers. It used to develop applications of all sizes on the web and mobile, as well as to develop enterprise-level applications and work with Big Data.

• Java becomes the 3rd most popular programming language and always remained in the top 3 lists in the next two decades. Here is the long-term history of Java in the popular TIOBE ranking:

Job Market:

According to Indeed, Java is the second most demanding programming language in the USA with 69 K Job posting in January 2020. Also, Java developers earn the 6th highest annual salary ($104 K).

According to the StackOverflow Developers (2019), Java offers modest salaries after a few years of experience.

Virtually any business today needs an Android App due to today's high Android user demand. This opens up a great opportunity for Java developers. It used to develop applications of all sizes on the web and mobile, as well as to develop enterprise-level applications and work with Big Data.

As a beginner, you should learn Java to build a powerful server-side application. we can create projects of any complexity in Java; It has tools, technology, and community to support.

If you are looking for a development-based job at a large organization, Java is the recommended language. This opens up a great opportunity for Java developers.

3. C++

C ++ is a primary language used on Investment banks and other buyer companies. It has been heavily used in creating high-performance trading applications.

Some advantages: high interactivity, have close proximity to logical thinking, and model diversity.

C/C++ is also widely used by competing developers because it is extremely fast and stable. It is used for developing VR, gaming, and computer graphics applications.Most operating systems have low-level systems, file systems, etc. are written in C / C ++.

Like Java, C++ is also constantly modernizing and adapting itself with changes in Hardware or Ecosystem. C++ also gives full control over the underlying hardware and can run on every platform and take advantage of every kind of hardware, whether it is GPU, TPU, Container, Cloud, Mobile devices, or Microcontroller.

Popularity:

C++ is the second oldest programming language in this list and ranked 4th in the TIOBE programming language ranking:

Job Market:

According to Indeed has ranked C++ as the 4th most demanding programming language with 41 K job posting. Also, C++ developers earn $108 K per annum.

This year, C++ grew in popularity by 16.22% compared to last year with almost 37,000 job postings.

Although C++ is facing massive competition from modern programming languages like Rust or Go, it is still generating stable interest in the last five years:

A survey from StackOverflow , C++ developers can draw a higher salary compared to Java, albeit with a longer experience. The average salary is nearly $91,000 per year.

As C++ is still demanding language for so many desktop applications. So many companies develops interface using this. You can grow with the company and can look for secured future for long term.

If you study C ++, you can work in companies that provide support or production in mobile hardware and applications. Companies like Intel, Nvidia, etc. offer lots of job opportunities for C / C ++ developers.

• 3D Development

• .Embedded Developer

4. Swift

Next on the list is Swift. Swift is a synthetic, open-source programming language developed by Apple Inc. 

It is advanced based on the structure of Objective-C, Swift is influenced by Python and Ruby and is designed to be beginner and user friendly.

It is considered to be a replaceable, faster, more secure language, and debug than Objective-C. Swift requires less code, helps accelerate the app development process.

Swift has propelled to top 10 lists of most popular programming languages by TIOBE index 

Job Market:

Indeed has ranked Swift as the 9th most demanding language in the USA with 6 K openings. In terms of Salary, Indeed has ranked Swift in 2nd place with $125 K yearly salary.

StackOverflow developer survey has also revealed that Swift developer can earn a high salary with relatively fewer years of experience compared to Objective-C.

If you're looking to create apps on iOS developers' smart devices, I suggest you consider learning Swift- a powerful programming language for macOS, iOS. On its own, Swift is a great choice for making mobile apps, and learning how to code Swift is definitely a skill that’s beneficial for your career path when acquired.

Swift will garner a lot of attention if placed in one’s resume. But Swift is just a Tool, without understanding the Concepts and Problems it can be used to solve, it pretty much narrows down to owing a Car when we cannot drive. So, future prospects of Swift is Good, provided, if we know what we are going to do with it.

5. Go

Last but not least!!, Like Swift, Go is only the second programming language from the last decade in this list.

Go is a comparatively less-heard but equally popular open-source programming language which was developed by Google in 2007. Go is perfect for minimal web applications, APIs, and web servers. It automatically provides support for programs that may exchange information while running simultaneously on different computers. It is also one of the fastest growing programming languages of the past few years. Some of its features include memory management, C-like semantics, high performance and modern data structure support

Its features offer a CSP based message-passing concurrency via Goroutine (lightweight Green thread) and Channel. The biggest USP of Go is its language design and simplicity. It has successfully combined the simplicity and productivity of Python and the power of C. Go has embedded Garbage Collector (albeit not as mature as JVM garbage collector). Go developers can write system programming with the safety of Java, Python.

Like Swift, Go has also seen a meteoric rise in popularity. In almost all popular programming languages comparing websites, Go ranks high and has surpassed many existing languages where Go ranks 14th (TIOBE index, 2020):

StackOverflow (2019) has also ranked Go as the 13th most popular Technology (10th most popular programming language).

Job Market:

Indeed has ranked Go as the 10th most demanding language with 4K openings in January 2020. In terms of salary, Go is ranked in 9th position:

GO as one of the highest-paid programming languages ranked by StackOverflow in 2019

Go has definitely picked up if you know where to develop. Companies such as CloudFlare, Dropbox, Docker, etc. are all looking to Go to build backend and middleware systems. Most importantly, learning Go means that you'll be exposed to a new concurrency model and a different flavor of code. This is inherently more useful than picking what to learn based on current popularity.

When we talk about scalability, concurrency, we talk about Go as well, apart from other very good languages. Go has its own set of uses and its not a right tool for prototyping or a replacement for some CMS. Point is you need to understand what it can do and how you can implement it in your projects/company now or in future. Learning curve is a bit steep, there is a crunch of resources and tutorials on Internet.

If you master C, C++ or Java , Go (or virtually any other scripting language) is very easy in comparison. You'll have no problem learning it if it does become relevant
