Effective variable naming in JavaScript involves using 'let' and 'const' instead of 'var', choosing clear and descriptive names, adopting camel case convention, using uppercase for constants, avoiding single-letter names, using plurals for arrays, and prefixing boolean variables. Establishing and adhering to a naming convention improves code readability and maintainability.
