This code makes it easier for other developers to read and understand. Similarly, W3Schools recommends using camel cases for variable and function names and single quotes in JavaScript.

Following consistent code style guidelines makes collaboration with other developers easier. It’s easier to read and understand each other’s code when everyone follows the same rules.

Proper Error Handling

Correct error handling is critical to ensure that your code runs smoothly and can handle unexpected errors. W3Schools offers examples and best practices for dealing with errors in various programming languages.
