How can you use JavaScript to follow coding standards?

Implementing a code formatter like Prettier not only standardizes code style across a project but also minimizes debates among team members about code formatting. This leads to faster code reviews and ensures that the team's focus remains on logic and functionality rather than styling.

Employ tools like Prettier or ESLint's formatting rules to automatically format your code according to predefined standards. This helps maintain consistent code style across the project and reduces the need for manual formatting.

*Fasters and Efficient code reviews* - As the code formatters enforce a consistent coding style throughout the codebase. This consistency makes it easier for reviewers to read and understand the code, leading to more efficient code reviews. - Also, reviewers don't need to take time to check coding standards/styles, so they can spend more time on substantive aspects of the code, such as architecture, functionality, and edge cases. This can lead to faster and more productive code reviews.

Linters and formatters like ESLint and Prettier can help you code in a CLEAN way and follow coding guidelines. It will prevent you from running into errors and unused/redundant code which may impact performance later. Sometimes JS code can be very messy due nested callbacks and return statements, to help you understand and not cause any errors, formatters can come in handy.

One of the best practices about code formatting in editors is code formatting on save. it format open windows on save to ensure that all code you write is formatting always .

Adhere to established JavaScript style guides such as Airbnb JavaScript Style Guide or Google JavaScript Style Guide. These guides define best practices for coding conventions, naming conventions, indentation, spacing, and more.

Adopting a well-known style guide, such as Airbnb's JavaScript Style Guide, can expedite the onboarding process for new team members. They can quickly align with established conventions, ensuring the team moves in harmony and minimizes the learning curve for incoming developers.

Start by selecting a widely accepted JavaScript style guide like Airbnb, Google, or the Standard style. Ensure your team agrees on the chosen style guide to maintain consistency.

Actually a style guide is tools but following a rule is the main gain. when you always write code with rules you do that in the right , trusted way and increase readability of your code . finding errors and pitfalls in code is low cost. it's like a special language in coding

Adhering to a style guide, such as Airbnb's JavaScript Style Guide or Google's JavaScript Style Guide, provides a set of standards for writing clean, understandable JavaScript code. Following these guidelines helps in maintaining code quality and consistency, especially in team environments.

Integrate a linter like ESLint into your development workflow to identify and flag code that violates coding standards. Customize ESLint rules based on your project's requirements and coding standards to catch potential issues early during development.

Integrating a linter like ESLint into JavaScript projects significantly improves code quality and adherence to coding standards. ESLint thoroughly analyses code, catching syntax errors, bugs, and performance issues early in the development process. By enforcing rules from a style guide or custom configuration, ESLint promotes consistency and readability across the codebase. For example, it can flag unused variables, enforce indentation rules, and detect potential security vulnerabilities. Moreover, ESLint's versatility allows customisation with plugins and rules tailored to project requirements and team preferences.

ESLint also serves as a mentor-in-a-box, guiding developers towards best practices and away from potential pitfalls. By integrating it with the development environment, real-time feedback allows developers to learn and adapt, making the codebase healthier with every commit.

ES Lint has a huge ecosystem of rules to enable beyond the default configuration, which people overlook. Your team can add any custom rule whenever they want, for whichever framework they use. Just the other day, I discovered the "antfu/case-police" plugin, which detects incorrect cases in common names like "TypeScript", not "Typescript", and "macOS", not "MacOS". Something as simple as this can be extended to any rule, especially if your product has a specific casing you want to follow. So, if you want to correct a misspelling of "Sharechat" to "ShareChat", then you can extend this and make your own plugin! The options are limitless!

Using a combination of TypeScript and ESLint has been a huge confidence booster with refactoring large pieces of code. When working with multiple libraries, it will identify places where you may have forgotten to update naming after a renaming refactor. It helps find problems with code that are easy to miss. It also helps with the onboarding process when getting a junior developer started, since you can easily view details in your IDE, and often can easily fix it with that context.

What's our end goal here ? To offer the best User experience there is right ? And what better way to do that than to make coding easier on ourselves ? Using modern tools is a necessity, not only it makes coding way much easier, but also saves a lot of time !

If a company does not use a JavaScript framework and is doing everything in vanilla JS, it is a huge tell for a healthy development environment. If you aren't learning and evolving, then you are behind. Prioritizing developer experience by implementing modern features does not only improve company culture, it reduces bugs and increases readability.

Certainly, these modern features are quite helpful in making JavaScript code easier and maintainable. Would also like to add a few more features to the list like Default Parameters, Map and Set Data Structures, Arrow Functions, Generators, Array Methods, Web APIs, Type Checking with TypeScript or Flow, Webpack, and Rollup.

Utilizing modern JavaScript features not only leverages the best that the language has to offer but also often results in happier developers.

I would also suggest using Typescript, if you’re starting a new JavaScript project. It takes a little more effort to setup, but it can really save you time in the long run. It gives you more visibility with the objects and functions your working with. A fully typed code base makes it easier to identify errors, which will make updating or adding features easier. And because there is more visibility in the code you’re writing, it can make working with other devs or joining a long running project simpler.

Implementing tests in JavaScript, using frameworks like Jest, ensures your code adheres to standards by validating functionality and detecting bugs early. Unit, integration, and end-to-end tests not only uphold code quality but also instill confidence in your work. My approach blends rigorous testing with continuous integration, allowing for iterative improvements and fostering a culture of excellence in front-end development. This methodology not only enhances reliability but also streamlines the development process, making it more efficient and aligned with best practices.

-Test small units of code. -Use the Arrange, Act, Assert pattern. -Keep tests short and simple. -Cover all possible cases. -Use assertions to check expected outcomes. -Use a testing framework. -Run tests regularly.

how can you write code without a test ? are you God in coding? tests are like sensors you install between your code to show you the errors . it forces you to write clean code , if you can't write a test for part of your code , sure that you write bad code . test can be a quality control platform for your project , write test , run code , if you find bug first write test to fail base on bug and then fix bug and again run test to be pass . then you never find this bug again whatever you change again your code , it's there , a sensor for that bug

Testing is an essential aspect of software development that might be perceived as tedious by some developers. However, with the advent of AI-assisted tools, the process has become more streamlined, eliminating barriers to comprehensive test coverage.

Writing tests for your JavaScript code, using frameworks like Jest or Mocha, ensures that your code behaves as expected. Tests act as a safety net, allowing you to refactor and add new features with confidence.

My rule of thumb: Always add comments explaining the high-level behaviour or role of a function or a block of code, but rarely about the implementation itself. Specific function names can often be descriptive enough to explain the behaviour (some may argue), but the return type may not be clear enough from the context. Using TypeScript solves many problems here, but adding a helpful comment about the "context" in which this function runs is usually better and reduces cognitive load.

Documenting your code with comments and using tools like JSDoc helps explain the purpose and functionality of your code segments. Good documentation is invaluable for maintaining code, onboarding new team members, and facilitating open-source contributions.

Create clear and comprehensive documentation for your JavaScript code. Comments, README files, and inline documentation help others (and future you) understand the purpose, usage, and inner workings of your code. Consider it as writing a story – make it engaging and informative to captivate your audience.

Based on my experience, adhering to JS coding standards not only enhances consistency in a project but also expedites the code review process, minimising potential style conflicts. Tools like Prettier and ESLint have proven their value in maintaining code quality. However, overlooked practices include effective code review strategies and incorporating CI/CD to ensure standard adherence throughout the development cycle. Additionally, smart refactoring strategies, a focus on performance optimisation, and security considerations are crucial aspects supporting project evolution. Over time, emphasis on team collaboration, effective communication & resolving design conflicts becomes key to successfully implementing sustainable coding standards.

Refactor Legacy Code: ? Gradually refactor existing code to adhere to the coding standards. ? This may involve fixing linting errors, updating formatting, and adding missing documentation. Lead by Example: ? As a developer or team lead, set a positive example by consistently following the coding standards in your own code

Stay informed about evolving coding standards and community best practices. Regularly update your tools and libraries to leverage new features and improvements. Consistently seek feedback from peers and the community to refine your coding style and ensure your JavaScript meets industry standards.

Teaching and Leading: I would love to add that Teaching and leading others is a powerful way to reinforce your understanding of coding standards. Here's why it's beneficial: Reinforces Knowledge: When you teach coding standards to others, you reinforce your own understanding and often gain new insights. Explaining concepts to others requires you to understand them deeply. I started teaching TypeScript and this helped me a lot to improve my own coding standard and understanding as well, even I am grateful to say that the responsibility to teach others made easy for me to understand some very deep concepts, which I can't master on my own without teaching.

In addition to expected uses such as linting to analyze your code for potential issues and enforcing your particular coding standards, you can also take advantage of modularization. Modularization, which is breaking your code into smaller modular components, provides a clear and single responsibility for any single given component, making your code easier to read and maintain.
