3. Use descriptive variable names that are easy to understand and remember, as this will make it easier for other developers who may need to work with your code in the future.
4. Make sure that all variables are declared before they are used in order to avoid errors caused by undeclared variables or functions being called before they have been defined.
5. Always use semicolons at the end of each statement, as this helps ensure that your code is interpreted correctly by browsers and other programs that may need to parse it later on down the line.
