How to Pick the Right Course
There are so many courses available online for free that it becomes difficult to choose the right one. Here is a guide to help you:
Check Your Current Level: If you are an absolute beginner, then start from the introductory courses on programming like "Introduction to Programming Using Python" or "Java Programming Fundamentals." If you are at the intermediate level, consider courses that include more advanced topics.
Evaluate Your Goals: What do you wish to achieve from learning any programming language? If you are seeking to develop for the online community, good picks might be "Web Development with JavaScript" or "Introduction to Ruby Programming". If you have an interest in Data Science, then take a look at "Data Science with R."
Look through the content of the course to ensure that what you want is offered. Some may be more theoretical; others may contain hands-on projects and exercises.
Check Reviews and Ratings: Especially on platforms like Udemy, this course has user reviews and ratings that give you an idea of the quality of the course and the teaching style of the instructor.
Consider Time Commitment: Some courses range from just a few hours to several weeks. While others are more comprehensive, select the courses based on which course will fit most in your calendar and at what pace you work best.
Learning any programming language can never be an uphill task anymore with free online courses available in abundance across different portals like Udemy and MyGreatLearning. From basic concepts to the expansion of knowledge, the courses can be very resourceful in reaching your goals related to programming. Availing these free courses can make a person knowledgeable enough to move on to the highly technical world and, in turn, have many more better job opportunities available.
1. Which programming languages are best for beginners?
From its simplest form, Python, and Java are highly recommended for beginners. Since they are both readable, have scours of people in large communities, and are resource-intensive, then the two are perfect. However, beginners can start with Python since it is very simple, especially in its syntax, hence best for beginners.
2. Are these free courses enough to get a job in programming?
Even though free courses are a great grounding, eventually to get a job requires further learning, practical experience, and sometimes even further certifications. The courses have to be supplemented with projects, internships, or advanced paid courses to build a competitive portfolio.
3. How long will it take to learn a programming language?
That depends on the complexity of the programming language and your learning speed. For example, you can master the basics of Python in a matter of a few weeks, but to become a professional, you may need to invest months of practice and complete several projects in Python or work with Python libraries.
4. Can I learn two different programming languages at the same time?
While one can learn more than one programming language at one go, it's usually more effective to work on one language before developing a good base and moving on to another.
5. Do I need to have any sort of background information before taking these courses?
Most of the courses on this list are relatively 'beginner-friendly,' and you do not need to know the first thing about programming. That's said; basic familiarity with computers and a little mathematical study go a long way.
