Top 3 Programming Languages to Learn During Lockdown

 

According to Google trends, Python, JavaScript, and Java have been voted as the top programming languages to learn in 2020, across several surveys and studies. 

Python

Python is widely accepted as the best programming language to learn first. Python is known to be a developer friendly language, free of clutter, with no curly braces, no classes, and no public/private modifiers. Python is fast and easy to use and deploy. Instagram, YouTube, and Pinterest are all built-in Python, while a lot of start-ups are utilising Python as their primary backend stack. This opens up a huge opportunity for those trained in Python. 

Pros:

  • Creating and using classes and objects is easy thanks to OOP characteristics
  • Extensive library support
  • Free of clutter, focusing on code readability
  • Ideal for programming beginners
  • Can be used to build frontend and backend applications
  • Has the ability to scale even the most complex applications
  • Ideal for building prototypes and testing out ideas faster
  • Abundance of open-source libraries with community support
  • Provides support for a multitude of platforms and systems

Cons:

  • Not suitable for mobile development
  • Slower run-time 
  • The database access layer not suitable for large-scale software development
  • Threading isn’t good because of GIL (Global Interpreter Lock)

Java

Java has been a popular starting point for developers for decades. Known to be extremely stable, Java is widely used for building enterprise-scale web applications and Android app development. Thus, Java knowledge is essential to any brand or organisation wanting to reach the billions of Android users. Well-known brands like Uber, Twitter and AirBnB use Java in their tech stack. 

Pros:

  • Used in enterprise software applications
  • Android development
  • Plenty of open-source libraries and huge community
  • Automatic memory allocation and garbage collection
  • Follows the OOP paradigm
  • Has the stack allocation system
  • Highly secure
  • Offers a wide range of APIs for accomplishing various tasks, such as database connection, networking, utilities, and XML parsing
  • Supports multithreading

Cons:

  • Verbose code can be confusing for beginners
  • Single-paradigm language
  • Expensive memory management
  • Memory-consuming makes it slower than natively compiled programming languages
  • Older language not ideal for startups and cutting-edge technologies

JavaScript

JavaScript is widely recognised as the “frontend” programming language, often used to design interactive frontend applications. These days, many organisations, particularly startups, are using NodeJS, a JavaScript-based run-time environment, for server-side scripting- running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. If working for a cool startup is your dream, consider taking a  JavaScript certification course.

Pros:

  • Job opportunities
  • Client-side JavaScript is fast and runs immediately within the web browser
  • Gives a rich and dynamic interface to a website
  • Highly versatile
  • Plenty of resources and extensive community support
  • Beginner friendly
  • Supports both backend and frontend development
  • Runs fast due to reduced website server demand by virtue of being client-side
  • Regular updates via the ECMA specification
  • Several add-ons, such as Greasemonkey, for extending the functionality
  • Simple implementation
  • Used for building a diverse range of applications
  • Works exceptionally well with other programming languages

Cons:

  • Constantly changing
  • Allows only single inheritance
  • Code executed on client-side is generally exposed causing security concerns
  • Might be interpreted differently by different browsers
