What is Maintainable Code? Maintainable code is basically the amount of time it takes a developer to make a change and the amount of risk that the change could break something.
More maintainable code allows for easier changes which results in faster changes and a lot less risk. A lot of these tips have been documented hundreds if not thousands of times before, if you want to be a good developer you need to start following these sorts of ideas.
Write Code that is Easy to Read Reading code can be a challenging task — remember the time when you were learning how to read and how you struggled with each new word and then eventually each new sentence and so on.
As you gain experience as a developer, you gather an incredible amount of intuition about what code will do. So, what does this mean?
It means that we need to write for the experience levels of our readers and also focus on doing the right things.
This is a balancing act, and it can be really tough — it means we need to gradually introduce change. Follow a convention Code should be consistent in style to make it easier to follow and easier to change.
Following the idioms of the language is also a good idea as this will dramatically help onboard each new developer that gets added to the project.
Do not try and blindly force a language to follow the idioms of another language. For example, a lot of companies developing mobile apps expect their Android Code to work like their iOS Code — but they are very different languages and environments. Give Meaningful Names Descriptive variable names can go along way in making things easier to read and to understand.
Public methods that are getting called by other methods should have obvious parameter names and they should ideally be in an obvious order.
Day by day, programmers are able to get more done in less time. With today’s high level languages, development environments, tools and the “rapid application development” mindset, both programmers and managers have become accustomed to extremely fast development cycles.

It's stupid. If I wanted to write to express myself I would have been a writer. The whole idea of my art is to say things visually. Why can't people just look at my art and take away whatever experiences they will?
Where possible, use enumerations or constants instead of checking if a String is equal to another string. For example, in code that controls what navigation a user has based on their role, you should have the Roles as Enumerations instead of just checking is User.
Write Small Classes and Functions Long functions have the potential to make code very difficult to understand. Long functions or long classes are usually a symptom of far too much responsibility.
Common and relatively easy refactorings to do can be moving the logic from switch statements into multiple functions.
For Example, say I had a switch statement that had a dozen or so lines per case statement. I should be able to move quite a bit of that code into little functions that my large function can call. Eventually, maybe I can move some if this logic into separate classes that implement interfaces and a factory could return the correct one.
Automated testing can help significantly reduce the costs to make changes and help more it far more obvious when there are problems.Gallery of How To Write Beautiful Meaningful Christmas Cards Kikki K Blog Card Writing Blog Detail 1 Card Stationery Picture 71 / user ratings Related Posts of .
