_Learning never Ends for a programmer_By annonymous Coder

The most important thing is that a programmer never stops learning. It is a lifelong process.

The method of learning things keeps changing from books, online courses, documentation to real-life experience. It is totally a fun experience to learn new things and help in creating a better tech for the future.

Even senior developers with 10+ years of experience learn a new programming language if they need to use that.

Share your feeling about being a programmer in the comments.

Learn Coding online vs offline (by books)

I was often confused in my early days of coding whether to learn computer programming online or offline(by books or coaching institute).

Both have their own pros and cons and you need to decide for yourself based on these facts.

Learn Programming Online

This is my preferred way to learn new things in programming. The main reason is that there are thousands of courses available to choose from. The only problem is that it is often difficult to choose the right one.


  • Thousands of courses are available to choose from.
  • Learn From anywhere
  • Online Support available
  • Regularly Updated


  • Confusing to choose the right course
  • Confusing to choose the best website to learn coding
  • Support is available but often Slow
  • High-speed internet needed for video courses
  • Procrastination (a great problem)

The all-time favorite domain of programming that has attracted millions of developers to experience the beauty of creating Websites.

This is an ideal choice to start with if you want to create something quickly that real peoples can use in their daily life. Unlike other software, you don’t need to have a big team to work with you.

Several examples exist that verify that even an individual can create a website that may be useful to millions (or more maybe).

This is also the most popular choice as of now to leave a 9-5 job and create a source of passive income.

The web developer Bootcamp course by Colt Steele on Udemy is the best web development course for learning full-stack development web development. This is the course that I will recommend for new programmers to learn coding online in web development.

Now, let us know how to start with web development.


It is the skeleton of every webpage. Just right-click on any webpage and view its source, you will see a whole lot of HTML code.

HTML is a markup language. It is important to remember because interviewers often ask this to test your knowledge. HTML only defines the structure of any webpage in a specific format.

HTML is very easy to learn with some practice.

W3School is a great place to start with HTML for free.


The main purpose of CSS is to provide style to the web pages. If HTML is the skeleton of the webpage then CSS is the skin for that page.

Learning CSS is easy and doesn’t require much effort.

The HTML CSS Course by Jonas Schmedtmann on Udemy is the best course to learn HTML, CSS online at a minimal price.


It is known as the verb of the webpage.

Javascript defines all the actions of any webpage. It defines how the website will respond to certain user interactions like clicking a button, scrolling leaving the page, and many more.

Javascript is the most popular technology according to StackOverflow survey 2019.

Learn HTML, CSS, and Javascript on Coursera.

Backend Technologies

It is part of any website that is not visible to normal users. It powers the website with various features that provide easy management of its content.

Backend is built for admins, developers, and other users that contribute to the website.

There is no particular way from here. You have to choose from various options available according to your need.

Here are some of the popular backend technologies.

  • Node.js
  • Django
  • PHP
  • Ruby-on-rails

Mobile App Development

Mobile App Development

Mobile App development is in a boom right now. It provides a platform to share your application with millions of users worldwide.

There are two major operating systems in the mobile world and they are Android and iOS. Both operating systems have large numbers of users which motivates developers to create useful Apps for them.

Both require a different programming language to code their applications. However, in recent years several technologies came into existence that allow you to create Apps for both Android and iOS with the same codebase.

Here goes the list of programming languages and frameworks to start learning to code Mobile Apps.


Java is extensively used in developing Android apps. It is the official language to code android Applications.

Java is easy to learn and was the most popular programming language for a decade.

You can learn java programming from this online course Java Course by Tim Buchalka on Udemy (recommended as best java course for absolute beginners).

Here are some Free Courses to learn coding in Java for free.


It is mainly used for iOS and macOS programming. If you have an interest in iOS app development then you can learn the swift language.

One thing to remember is that you need an Apple developer Id to develop iOS apps which cost 99 USD annually.


JavaScript is everywhere, from the web to mobile phones.

React Native is a Javascript library by Facebook which is based on React.js to create mobile applications. It is easy to learn if you already have knowledge of Javascript and React.js.

There is an ongoing debate that whether React Native is really Native or Hybrid.

You can read more about Native vs Hybrid Mobile Applications here.

Before learning React native, you need to learn Javascript and React.js.

You can learn to code in React native from React Native – The Practical Guide on Udemy.

You can learn to code in react native for free with these courses.

Software Development


This one is a real programming language that requires years of experience to master. Mostly preferred in programming interviews by tech giants.

It is often recommended to be learned as the first language to learn for Computer Science students. If anyone becomes an expert in C++ then learning other programming languages is just a matter of time.

If you free to learn new things then investing time in C++ is worth it.

QT framework of C++ is used to create cross-platform desktop applications. You can create software supported by Windows, Mac, and Linux.

The best course to learn coding C++ online is by this C++ course on Udemy.

You can also learn C++ for free with these courses.


Java has a toolkit Swing to create GUI-based software. It allows developers to create beautiful software with ease.


Easiest programming language to learn coding.

It was my first programming language that I used to create something useful. It is the second most popular programming language after Javascript according to StackOverflow survey 2019.

There are plenty of jobs available for python developers. It is one of the fastest-growing programming languages that developers prefer to use.

Tkinter and PyQT are the most popular frameworks in Python to create GUI-based software applications.

The best course to learn Python programming is Python Course by Jose Portilla on Udemy. I have learned python from this course.

Here are some best resources to learn python programming online.

Javascript library – Electron.js

Another popular javascript library. Released in 2013 became one of the best options to develop cross-platform software applications using web technologies like HTML, CSS, and Javascript.

The most important thing is strong data while creating any type of software or web application. There are many types of databases available and they are developers choose a particular according to the type of data.

These are the two major types of databases that are most popular right now.


SQL is the third most used language according to StackOverflow 2019 survey. It stands for the structured query language.

SQL is widely used where data is in a specific format (structured data).

SQL was introduced in the 1970s and is one of the most popular databases used by major corporations.

The payscale and jobs count in SQL are higher than in other technologies.

You can learn SQL from this database design course by educative.

In recent years we have seen rapid development in the field of Artificial intelligence. They are used almost everywhere like spam classifiers, recommenders systems, and many more.

Artificial Intelligence means a system that can simulate the human mind that can think and acts like humans.

There is wide scope for Artificial Intelligence in the future because many revolutionary AI projects are under development. Some examples uses of Artificial intelligence are self-driving cars, chatbots, voice assistance, automate characters in games.

Learning Artificial Intelligence is not as easy as it seems because it requires a deep understanding of algorithms and maths (painful but true).

Here are two languages that are widely used in the field of Artificial Intelligence.

  • Python
  • R Language

Complete Some Projects

Now comes the most interesting part of learning programming.

After learning any programming language you must create at least one or two big projects. It is important because you will learn many new things which will enhance your knowledge and problem-solving skills.

If you want a Job once you have learned coding then you must create some interesting and unique projects. Interviewer always wants candidates that are creative and passionate about coding. Creating projects that are complex and the use of multiple technologies can have a very good impact on your interview.

One more benefit is that you become comfortable with the programming language in which you create the projects.

I was afraid to use React.js when I started learning it. However, after creating two to three projects it became my first choice for developing the frontend.

How to get Project Ideas?

Learn Advance Programming Concepts

This is important if you want to become a real programmer.

The only thing that differentiates a programmer from the crowd is an in-depth understanding and efficient use of data structures and algorithms.

Learn Data Structures and Algorithms to become a pro Programmer

This is the important step that most programmers skip in beginning and face its consequences later in their career.

It helps to write better code that is optimized for time and space which are very helpful in scaling the application in optimum resources.

You can start learning data structures and algorithms with this awesome course from Coursera.

What to do after Learned Programming?

Once you have finished your journey with learning, you can jump to the next step which is building a strong online presence.

Create an online Portfolio

You need to create your online page to showcase your skills.

Your portfolio should contain details about your works and yourself. This is not mandatory but has a good impression on the interviewer in job interviews.

Competitive Programming

After you have learned computer programming, you can participate in online coding challenges. They are very helpful in building a strong problem-solving base.

You will learn different ways to solve the problem at a specific time.

Competitive programming helped me a lot in getting comfortable with Python and Java.

Apply For Jobs

You can start applying for jobs after you have learned any programming language and completed at least one or two projects in that.

You can visit the jobs page (mostly all corporate websites have) to find available positions.

One thing you need to remember is not to lose hope even if hundreds of companies reject you. It is part of life especially if you are a fresher.

You will learn different things in the interview, but don’t forget to take a review of your performance by the interviewer. After the interview, you can ask for feedback in a polite manner.

Start working on your creative Idea

Did you learn coding to be an entrepreneur?

Best of luck buddy.

If you have some idea that you want to work on then you can start working on that. It is important that you build a team for coding because it is difficult to do all things by yourself.

Seek help from some senior developer or learn more about programming patterns and designs before starting any big project.


This was the list of full steps to learn coding online for free. You can choose to learn coding by offline resources as well.

I have listed the best resources to learn coding but you can choose your own preferred courses as you see fit. Everyone has a different style of learning new things and they may prefer one resource to another.

Remember one thing in programming:

Don’t learn the syntax, understand the logic of programming. It will help you to be a better programmer.

Programming languages change over time but concepts remain the same. If you have a good understanding of concepts then you learn new programming languages easily.

At last, it all depends upon your creativity and problem-solving skills which makes you a perfect programmer.
