These outcomes can bring down our confidence but actually, they will be solved with proper development practices. Here are 10 worthy habits to take a position in to write down cleaner and smarter code with less effort. Let’s start developing these habits now!
Learning Programming: 10 Misconceptions That aren’t True

There are many misconceptions and myths surrounding the art of programming. Many view it as employment.

1. Write Human-Friendly Code

Always remember that you simply aren’t just writing code for machines, except for your future self too. So it’s important to write down readable code. In truth, programming is like writing an honest poem.

Here are some tips to write down a friendly code.
Follow Consistent naming conventions

For example, if you name private variables with an underscore because of the first letter, you ought to follow through within the remainder of your code.

If you’re working collaboratively, discuss naming conventions before anyone touches the code.

However, most programing language may now have already got their own standard naming conventions either it’s defined by the core language itself or the community (e.g. PHP-FIG). So, most of the time, you don’t need to create your own naming conventions.

You can instead use a so-called linter or code sniffer to assist in enforcing and fixing your code to evolve with these standards. Here maybe a few of popular linters in some programming languages:

  • Ruby: RuboCop
  • Shell or Bash: ShellCheck
  • ESLint, and JSHint
  • Swift: Tailor, and SwiftLint

Descriptive Variable / Method Name

The variable and method name should perfectly describe what that code does. for instance, uncommon abbreviations like Sort_PT() could also be confusing: what does the PT mean?

There’s an exception though. Most of the programmers would already be conversant in the term “ID” for identity so we will always define a variable with the short form, “ID”.
Indentation And Line Breaks

Indentation is magical! With some simple tab keys, you’ll reveal the whole code structure and edit the code with a transparent understanding of how it’ll function.

For line breaks, use it when 2 codes on an equivalent line execute various things . as an example, it’s best to not chain CSS properties on one line — it complicates things.

2. Think Organization

On top of cleaner code, code must have a clean organized structure that helps with readability issues. it’s important to group your code to enable easy modification (if you would like to scroll up and down multiple times to seek out your affected section, you would like to figure on the structure)

Also, don’t throw all the code into one script. While it’s going to seem convenient to possess 8000+ lines of code during a file , debugging may be a nightmare when trying to recall method names. Always believe in the convenience of change.

The best practice is to separate code into different files consistent with their primary functions, for instance, manager, interface, animation, extension, etc.

Whenever possible, confirm the language only fulfills a specific purpose. If you’re writing an animation effect with CSS3, avoid writing jQuery animation effect, unless you’ve got a robust enough reason. And if you are doing, comment within the CSS file about the exception.

3. Planning Before Coding

It’s crucial to understand exactly what to try to before you hit the primary key. within the programming world, it’s important to plan ahead. Writing a hard and fast navigation menu is straightforward, but what if the menu must be responsive while having the ability to attenuate itself when visitors scroll down the page?

Begining to code without a transparent procedure in mind will often cause retries, burnouts, and a depression loop.
Plan Your Code

So rather than problem-solving and programming the parallel way, it’s far easier to work out the procedure first, then write an answer. let’s see some steps:-

  • Use Bootstrap as a responsive framework.
  • Create a navigation menu.
  • Add .navbar-fixed-top to the menu.
  • Create a jQuery script to resize the menu when the user scrolls down for over 200px.
  • If the user scrolls to the highest, resize the menu once more.


At now, you ought to discover other underlying issues, like how we should always resize the location logo and menu title consistent with menu size, or if we’d like to resize the dropdown menu also, or if the detection must be dynamic rather than fixed. Once you work these out, it’s a snap to urge the menu done.

4. Write Manageable Code

Trust me, you don’t want to vary many variables individually, line by line. I did, for 1 straight year. That was a humbling experience, and since then I even have learned to write down code that needs as few manual changes as possible.

How to achieve this? Use the Array. It’s perfect for storing multiple variables, and you’ll access those variables with convenience for loop or for every method.

There are even more dynamic ways to feature, arrange and retrieve data in certain languages, like List and LINQ for C#, so make certain to periodically inspect better features, libraries, or plugins for smarter data management.

Lastly, to avoid constantly modifying stuff in code, write highly independent code that will not break the whole system when new features or changes are applied. It’s called Loose Coupling. After optimization, the developer only must tweak code in 1 class rather than 3 classes for brand spanking new features.

5. Stop Overdoing Features

In development, it’s important to regularly remind yourself of the project’s main objective, and only add features that fulfill the aim. If you recognize the precise collection size, use Array. If List’s function can retrieve the info the way you would like, don’t use advanced LINQ.

Why develop a plugin once you hardly use that feature? simply because you’ll, doesn’t mean you ought to. Don’t waste some time. Remember the foremost time-consuming part aka finishing the project, is yet to come! Now, onto debugging!

6. Learn To Debug Smarter

Where there’s code, there are bugs. It’s impossible to possess a bug-free code solution, so debugging skills are highly wanted. the traditional trial-and-error method may go, but it’s slow. Too slow.

Debugging Tools

IDEs like Aptana Studio 3 and Xamarin Studio are even released with their own powerful built-in debugger, so investing the time to find out them can make your life much easier.

When unsure, put the log function into the code, like console.log for, and confirm it’s good with variable integration (instead of retyping variable names as a string or just ‘It works!’). the online is crammed with more advanced and specific debugging methods for each language.

7. Find A Stronger Editor

The right editors can assist you to grow in knowledge, and expedite project completion. no matter how experienced you’re , it’s strongly recommended for you to travel for editors with code completion, like Sublime Text, Visual Studio Code, and Aptana Studio 3.

Not only is that the feature very helpful for beginners to acknowledge and learn the syntax, but it is often utilized by professionals to see for possibly better codes or solutions. Do note, most IDEs only support code completion surely languages, so search for the proper one.
Feature Filtering

For instance, one thing I really like about MonoDevelop is its code template feature. With a custom shortcut key, you’ll output a self-defined code template from a common switch statement to a full-fledged manager-script. this is often great for giant-scale projects, so attempt to make this feature a priority during your editor hunt.

Other essential features to seem out for:

  • debugger
  • regex replace
  • macro
  • version control support
  • database support
  • split editing
  • layout customizer
  • WYSIWYG editor

8. Do Version Control

There will be times once you make an enormous programming mistake and need to travel back to an earlier version of code. Now what if your mistake involves several files within the codebase, and a few of them were modified days, or maybe months ago?

Revert to the first and update the code bit by bit while solving bugs? this is often counterproductive and why a versioning system is greatly essential.

Among several version control software, Git is that the hottest with an outsized number of documentations available online. With Git, you’ll keep as many revisions as you would like, diversify the file for a few code experiments, hunt the part of code you changed last time, and revert back to them whenever you would like.

Feels like overkill? Maybe, since it’s originally developed for team programming, but it’s also perfect for future personal projects. you’ll be hesitant because the Git is in itself such a lot to find out abreast of, even with the GUI version. But it’s more of a sooner or later thing (so better that you simply make it sooner), plus the online is loaded with many tutorials and guides to assist ease the training process.

9. No Extra Prototypes, Finish Current Project

Tedious coding and debugging can drain someone physically and emotionally. and a few folks are inclined to prototype our work even before it’s finished. While prototyping may be a beneficial behavior within the end of the day, it doesn’t help once you roll in the hay to flee from work.

A better thanks to losing some steam is to enjoy something totally unrelated to the work, exercising, gaming, reading (perhaps?) — you’ve got to stay your work life in balance. Anything but prototypes.

Developing applications are often a really stressful job. Nobody is ideal, and running into buggy code is fairly.

10. Always Learn Something New

In this field, you’ll get phased out fairly quickly. Many developmental approaches and programming languages even are declared obsolete within the past 10 years alone. albeit you graduate from a top university with a degree within the subject doesn’t make sure that you’re still primed for employment.
