'Pro'gramming Tips

Seriously are you trying to teach me how to write code?

Well, Not exactly.

Analyse First - Code Next!

Ever wonder what value could be added while analysing the problem before jumping to code? Of course you may be doing it! Make sure not to skip below

• Have a phase wise solution to achieve the target.
• Don't go with assumptions.
• Make sure to the solution gets reviewed by peers, go with justifications & accept feedbacks.

• Don't ignore negative scenarios, most of the people fail to foresee them, land them in bugs during testing phase.
• Last but not least... Use boards or Papers to simulate your programme before coding.

Functional Programming

• Are you writing a single function to solve the whole problem? Never ever do that.
• Break the complex function to small functions, accepts input to produce output & doesn't rely on any shared resources.
• Unit Testing made easy. Possible to achieve ??.
• Reusability.

Avoid Tightly Coupled Code

• Implement the class from Interface/protocol. This may not be applicable in all cases (ex: Utils)
• Avoid declaring class variables with concrete class types. Instead define them with interface type.
• Helps to develop scalable solutions.
• Dependency injection made easy, to support multiple runtime configurations.
• Enables to Mock & Again Unit Testing made easy. Possible to achieve ??

Tightly Coupled Code

/// Tightly Coupled 'FeatureView'


class ApiService {
    func fetchTransactions()
}

class FeatureView {
    var serviceLayer: ApiService // FeatureView
 is tightly coupled to APIService class
}

Loosely Coupled Code

/// Loosely Coupled 'FeatureView'


protocol ServiceProtocol {
    func fetchTransactions()
}

class ApiService: ServiceProtocol {
    func fetchTransactions()
}

class FeatureView {
    var serviceLayer: ServiceProtocol // FeatureView
 is loosely coupled to Service layer
}

Appropriate names

• Don't ignore giving right names to your classes, methods & variables.
• It is good to be both clear and brief as possible, but clarity shouldn’t suffer because of brevity
• In general, don’t abbreviate names of things. Spell them out, even if they’re long.
• Prefixes are an important part of names in programmatic interfaces. They differentiate functional areas of software.

Code Documentation

It Matters!

• Documentation is one of the must thing, we often ignore while programming.
• It adds value to the code & sometimes it even make us to rethink about the implementation.
• Its main objective is to make every other developer understands the code, even the actual developer is not around.
• Always follow the standard way of documenting the code as per IDE guidelines.

Unit Testing

???? No Excuses!

• Ensures the quality of the code.
• Helps to find bugs during early phase of development.
• Guarantees productive time.
• its the only way that can assure you peaceful nights ??

PR reviews

• Do get your code reviewed by your peers.
• Raise small PR that helps to get them reviewed quickly.
• Follow IDE suggested best practices while writing code.
• Accept as many comments as possible to see optimised code.

Do practice for better results. Thanks for the read, Will keep sharing more tips.

Happy Coding????
