10 Common Programming Mistakes That Every Beginner Must Avoid FunctionUp

Programming is fun but it can get quickly frustrating if you are a beginner-level programmer still struggling with your semicolons and brackets. Here are some Common Programming Mistakes That Every Beginner Must Avoid. If the initial days involve a lot of struggles, the beginner-level programmers start losing interest, develop a fear of coding or just take too long to master the basics. 

In this blog, we will take a look at some of the most common mistakes beginner-level programmers end up doing which are avoidable by following some simple tricks.

Since programming is logical, systematic, and sequential, a singular goal setting helps in avoiding clutter and messing up the work.

Here are the common programming mistakes that every beginner must avoid:

1. Multiple languages, frameworks, and technology

When people want to learn programming the first level of confusion they encounter is which program to choose. While some take that decision after careful deliberation few others end up putting their five fingers in five different pies. While it may seem tempting to focus on learning more than one language in order to optimize career opportunities, it is a sure-shot recipe for disaster if you are just starting. The better idea is to choose one language, stick to it, learn the basics and advanced level, master the real-world project application and then move on to the next language. A few guidelines to remember while choosing the language are:

  • For competitive programming, one can choose C++ or Java
  • For Machine Learning, NLP, or AI applications,  Python is an excellent language to learn
  • To learn website building HTML, CSS and JavaScript are the best bets
  • For placement exams, C++ and Java should be the focus
  • For software development, Java is a great option
  • Still unsure, play safe, choose Node.js

2. Revision Notes

Remember those revision copies you maintained at school to go through before your exams? Don’t drop the habit just yet. Maintain your revision notes while coding and you can always go back to them lest you forget concepts. 

3. Create a Learning Path

You need to identify your learning milestones, create a timeline to achieve them, and stick to them. Since programming is vast and learning even one language can throw you into a labyrinth, having a roadmap helps. Create one and follow it so that you have concrete learning and have time to move on to the next language without losing your mind. 

4. Applied Learning

Learning to program involves conceptual understanding but more than that the application of learning is super important so that you understand how codes work in real-life situations. We haven’t even started on debugging remember that. An ideal way is to pick up your topic of the day and try solving small assignments around those topics on sites like Leetcode, SPOJ, or InterviewBit. And yes, share what you learn, create your GitHub account, and put out your work for evaluation, criticism, and feedback. 

5. Back up, please

Do not forget to have a ready backup of all your online work. You can’t wait for your machine to stop working or for a hard drive to get corrupted and risk losing all your hard work in one swift blow. Blogger is a good place to store your tutorial note while more comprehensive work can be stored on GitHub. So buckle up and back up. 

6. No room for self-doubt

When you are a beginner-level programmer, there are two emotions you undergo. First, a rather common feeling is that of being overwhelmed by the sheer amount of work you need to put in and the next feeling is that of doubting yourself and your abilities after comparing them to those at the advanced level of learning. You need to remember that every step counts and therefore instead of a sinking feeling one must look at smaller steps and seek advice and motivation from those at more advanced levels. Your learning journey needs to happen at your pace. 

7. Multiple Practicing Platforms

While preparing for their placements, most beginner-level programmers tend to opt for more than 1-2 platforms for DSA practice and competitive coding. Many platforms penalize the nebiews who commit coding errors and that could play havoc with the confidence levels of new programmers. We suggest sticking to 1-2 platforms only and getting ample practice. Also ensure to first clear your basic concepts, strengthen your skills and then expose yourself to competitive coding platforms. 

8. Let’s talk about debugging

An important step that rookies often miss, is debugging their application. Beginner-level programmers have very little idea about the debugging process and end up skipping the step altogether therefore beginners should spend ample time learning what debugging is and developing their own methods to approach it. Debugging also helps in reasoning and problem-solving skills which ultimately makes initial coding better and therefore beginners should invest time to learn it. 

9. Never stop the daily practice

Coding is all about practice, practice, and then some more practice. Participating in coding competitions, hackathons, etc helps keep your momentum and allows you to better your skills every day. Never adopt the shortcuts and never be lazy about the formatting, correct indentation, appropriate variables, and functions with proper names.

10. Comment on your codes

It is important to comment on each line of code so that when you revisit them you can make a sense of what was done. Use pertinent, brief, and relevant remarks so that you are reminded of the purpose of the particular code line as soon as you see it. 

Well, those were all the tips on mistakes to avoid while coding and go onwards on their learning journey filled with confidence and purpose.
