Not once or twice have I heard things like, “Why should I follow this? It works just fine for me,” or, “I know what’s best for this project, why should I follow their conventions?”
It’s easy to ignore coding standards and conventions as unnecessary, especially when everything seems to be working well for you. But here’s the thing: a codebase with consistent styles and patterns isn’t just about personal preferences - it’s about creating an environment that’s easier to work with, understand, and maintain.
So, what’s the difference between coding standards and coding conventions? In simple terms, standards are formal rules that ensure code quality & consistency across projects, while conventions are agreed-upon practices for style and structure of a language or a project.
For example, a language convention in JavaScript or TypeScript is to use camelCase for variables, so you wouldn’t use kebab-case. On the other hand, a project convention might be to use camelCase for folder names, even though folder naming doesn't have a universal standard, unlike variables or functions. If the project adopts this convention, you should follow it.
An example for coding standards in action is using simple tools like ESLint (a linting tool that analyzes your code and provides feedback as you type) and Prettier (a formatter for consistent style). While these might seem trivial to you, they enforce coding standards and help catching common errors early, and it's much easier to review and maintain code that is formatted and well-organized.
But why does this matter? consistent code isn’t just about aesthetics - it makes the code easier to read & review. Imagine working on a large team where everyone uses their own styles. Reviewing code would become a nightmare, and onboarding new developers would take longer. Tools like linters catch issues early, and formatted code saves precious time during code reviews.

In the end, following coding standards and conventions isn’t about limiting creativity, it’s about making collaboration easier and creating software that’s simpler to maintain and grow. Think of it as a shared language - one that makes sure everyone on the team is speaking the same "dialect". That’s how great software gets built.
- SaaS architecture is compared to a high-rise building, handling scalability, user management, and security with a structure of user interface, server, and database. - Each SaaS service has unique features but shares a core structure. Additional sub-layers might be present depending on the service's complexity. - Multi-tenancy allows SaaS to efficiently serve multiple users from one app, providing cost and resource benefits. - Various platforms such as AWS, Azure, Salesforce, and Oracle offer distinct approaches to multi-tenant systems. - Understand SaaS architecture in real life through examples like Dropbox and Salesforce. Business apps like Slack and Trello exhibit SaaS applications in business. - There are SaaS architectural patterns and principles, like AWS multi-tenant SaaS, that can be used in designing SaaS architecture. - Resources, case studies, and literature to navigate architectural complexities are readily available online.
- Choosing the right language for backend programming is crucial, with Python and Node.js as two commendable choices. - Python is favored for its clean syntax, simplified development process requiring fewer code lines, and impressive data analysis capabilities, along with extensive library support. - Node.js is popular due to its non-blocking nature which allows simultaneous request handling, beneficial for real-time applications, and boasts a robust ecosystem of package management tools. - Backend architecture involves server configuration, databases, scripting, and site organization. - Different languages offer unique features in backend development; JavaScript handles numerous concurrent connections and tasks, PHP excels in dynamic content generation, and Golang supports concurrent programming. - Ruby and HTML differ in backend use; while Ruby has clear syntax and supports databases, HTML, being more front-end orientated, is less useful in managing data or communication. - A good backend language should manage complex tasks, efficiently interact with web servers, possess broad community support, and excel in server-side computing and network infrastructure handling. Choice depends on the nature and needs of the task at hand.
- Swift programming is beginner-friendly due to its simplicity and readability. - The core concepts of Swift programming include its powerful type systems: options, generics, tuples, and first-class functions. - Resources for learning Swift include Swift's Official Site, online Swift Programming courses, and Swift Playgrounds. - Hands-on practice examples of SwiftUI can be found in the Apple Developer app. - Swift 5.7 learning guide provides updates about changes and techniques in iOS app development. - W3Schools and online programming courses can enhance Swift learning. - Joining Swift's community and contributing to its open-source development can be beneficial. - Swift programming can be made compatible with Android and Windows using tools like Swift Android toolchain and by downloading Swift from the official site.
