KebabCase is a naming convention used in programming and web development where words are separated by hyphens. For example, the phrase "my variable name" would be written as "my-variable-name." This format is often used in URLs and CSS class names because it improves readability and helps avoid spaces, which can cause issues in code. KebabCase is similar to other naming conventions like CamelCase and snake_case, but it specifically uses hyphens instead of capital letters or underscores. It is particularly popular in languages like JavaScript and frameworks such as Angular for creating clear and consistent identifiers.
