Use strict mode
This will ensure that your code is executed in strict mode and any errors or warnings will be displayed in the console.
Use descriptive variable names
When naming variables use descriptive names that clearly convey their purpose. avoid using single letter variable names or generic names like x or data. instead use names that are descriptive and meaningful such as userName or userEmail. this will make your code easier to read and maintain.
Avoid global variables
Global variables can cause conflicts and unexpected behavior in your code. instead use local variables and functions whenever possible. if you need to use global variable use unique name that is unlikely to clash with other variables in your code.
Use comments to explain your code
Comments are a great way to explain your code and make it easier to understand. use comments to explain what your code is doing, why it is doing it and any potential issues or limitations. this will help other developers understand your code and make it easier to maintain and update in the future.
Use consistent formatting
Consistent formatting makes your code easier to read and understand. use consistent style for indentation, spacing and line breaks. this will make your code more readable and help you avoid syntax errors.
Use error handling
Use a linter
linter is a tool that analyzes your code and identifies potential errors and issues. use linter to check your code for syntax errors, coding conventions and best practices. this will help you catch potential issues before they become problems and make your code more robust and reliable.
