What programing language should I learn in 2021 for employment and future?

Home /

It’s the beginning of the year, a time when many technologists are considering which new skills and programming languages to find out. As you work out the simplest ways to expand your skillset, it’s worth watching which programming languages enjoyed the very best demand from employers over the past 60 days; which may help influence your decision-making.

Each programing language is meant for a selected purpose and has its relative merits and demerits. Also, the solution to the foremost useful programing language to find out is subjective and depends on your familiarity with coding. Irrespective, the subsequent 3 parameters are essential to narrow a language a choice.

  1. Job Opportunities within the chosen language.
  2. The popularity of the chosen programing language should get on an uptick.
  3. Your Career / Life Goals.

After collecting and analyzing many job postings from across the country, here is that the list, SQL topped the rankings, followed by Java, Python, and JavaScript. Other well-known languages, including C# and PHP, also made it into the highest twelve:

I will try to give you some clarity by giving some brief for some of the above-mentioned Programming Languages 🙂

–> SQL

SQL (structured query language) is important to database work (and backend programming); it had been designed for managing and querying relational databases, which were invented within the 1970s and popularized by Oracle. In recent years, companies in even the oldest-school industries have recognized the facility of organizing and analyzing data, resulting in an increasing need for technologists who can build and maintain databases—hence the necessity for SQL skills.

Created: SQL was developed at IBM by Donald D. Chamberlin and Raymond F. Boyce. This language was made available publicly in 1979.

Pros:

  • Powerful command language

  • Fast for retrieving data from multiple tables

Cons:

  • Difficult to convert data from Objects into database tables
  • It can only run on the only server, so increasing speed means upgrading hardware.
  • As SQL databases run on one server so just in case if the server pack up, then the database should not be accessed
  • Usage applications: utilized in Any Database

Salary: the typical salary earned by SQL Developer is $84,792 per annum within the US. 

Learning Difficulty: Easy

–> Java

Java benefits from years’ worth of heavy corporate usage. As companies roll out more and more products that utilize Java, they need to still hire developers skilled within the language so as to iterate and repair those products. Java is additionally ubiquitous in multiple contexts, including the online and mobile, so it’s not departure anytime soon (despite Google’s recent push to possess more developers to embrace Kotlin, which is positioned as something of a “Java killer”).

Created: James Gosling primarily designed Java at Sun Microsystems within the year 1996

  • Object-Oriented language
  • Java offers APIs for various activities like Database connection, networking, XML parsing, utilities, etc.
  • Powerful open-source Rapid Development tools
  • It is one of the simplest programming languages to find out that has a sizable amount of open source libraries

Cons:

  • Memory management in Java is sort of expensive
  • The absence of templates can limit you to make high-quality data structures.
  • Usage/Application: Java mostly used for developing Android apps, web apps, and large data.

Salary: a mean salary for any Java developer in United State is $101,013 per annum.

Learning difficulty: Learning Java is straightforward and easy.

–> Python

Python recently named the highest programing language of 2020 by the TIOBE Index, which tracks the relative popularity of programming languages. Python’s increasing use as a specialty language makes it well worth studying; start your journey by heading over to Python.org, which offers a handy beginner’s guide. If you’re more of a visible learner, Microsoft also features a video series, “Python for Beginners,” with dozens of lessons (most under five minutes in length; none longer than 13 minutes). And confine mind all the extensions and frameworks that make programming in Python that much easier. 

Created: Python language developed by Guido van Rossum. it had been first released in 1991.

Pros:

  • It is one among the simplest programing language to find out which supports multiple systems and platforms
  • Object-Oriented Programming (OOPs) driven.
  • Helps to enhance Programmer’s Productivity
  • It is one among the simplest coding language to find out that permits you to scale even the foremost complex applications with ease
  • Extensive Support Libraries

Cons:

  • Note ideal for Mobile Computing
  • Python’s database access layer is a bit underdeveloped and primitive.
  • Usage/Application: Web and Internet Development, Scientific and Numeric applications, Desktop GUIs, Business applications. it’s widely utilized in AI and Machine Learning space.

Salary: a mean salary for any Python developer in United State is $114,383 per annum.

Learning Difficulty: Easy

–> Javascript

Created: JavaScript was earlier called LiveScript when it first shipped in with Netscape Navigator 2.0 in September 1995. Later, it had been renamed JavaScript.

Pros:

  • Client-side JavaScript is extremely fast because it is often run quickly within the client-side browser
  • JavaScript is one among the simplest coding language to find out which is comparatively simple to find out.
  • It is one among the simplest programing language to find out which may work smoothly with other languages and may be utilized in an enormous sort of applications.
  • Grease monkey support to write down snippets of JavaScript which may execute on specific sites 

Cons:

  • JavaScript only allows single inheritance, so multiple inheritances aren’t possible
