- Keep code readable and maintainable: Use clear, descriptive variable names and structure code using indentation, white spaces, and consistent formatting.
- Use modular design patterns: Break code into reusable and modular components to make it easier to test, debug, and maintain.
- Declare variables with ‘let’ and ‘const’: Use ‘const’ for variables that shouldn’t be re-assigned and ‘let’ for those that need to change.
- Use arrow functions for anonymous functions: Arrow functions are more concise and preserve the value of ‘this’ from the surrounding scope.
- Handle errors and exceptions: Use try-catch blocks to handle errors and exceptions in your code.
- Avoid global variables: Global variables can lead to naming conflicts and are generally considered bad practices.
- Use strict equality operator (===) instead of abstract equality operator (==): The strict equality operator tests for both type and value equality, while the abstract equality operator may perform type coercion.
- Use a linter: A linter helps enforce coding standards and catch potential bugs before they become a problem.
- Write tests for your code: Automated tests help ensure code quality and catch regressions.
