Javascript variable naming rules

in javascript, variable naming follows specific conventions to ensure clarity and prevent errors. variable names must start with a letter, underscore (_), or dollar sign ($), but cannot begin with a number. they can include letters, numbers, underscores, and dollar signs, making them versatile for various naming styles. variable names are case-sensitive, meaning "variable" and "variable" are distinct identifiers.

while there are no strict length limits, it's advisable to keep names concise yet descriptive to enhance code readability. avoid using reserved keywords, which are predefined by javascript, as they have special meanings in the language. additionally, adopting a consistent naming convention, such as camelcase or snake_case, can improve code maintenance and collaboration. overall, following these rules helps developers create understandable and manageable code, reducing the likelihood of bugs and improving collaboration within teams.
