lowerCamelCase

LowerCamelCase, commonly referred to as camelCase, is a naming convention in which multiword identifiers are written without spaces, and the first character is lowercase. Each subsequent word begins with an uppercase letter to indicate boundaries, for example: myVariableName, parseJsonResponse, totalCount.

It is widely used for variable and function or method names in languages with case-sensitive identifiers, such as Java, JavaScript, Kotlin, and Swift. In these ecosystems, lowerCamelCase contrasts with UpperCamelCase (also called PascalCase), which capitalizes the first letter of every word and is commonly used for class names.

In addition to camelCase, other naming schemes exist, notably snake_case and kebab-case. Snake_case uses underscores and is common in Python and some database schemas, while kebab-case uses hyphens and appears in URL slugs and CSS class names.

Acronyms and initialisms can complicate the rule about capitalization. Some style guides render common acronyms as words, yielding parseXml or jsonResponse, while others keep the acronym in uppercase, as in parseXML or JSONResponse. The key is consistency within a project.

In summary, lowerCamelCase is a practical convention for naming identifiers that are not types, emphasizing readability and word boundaries by capitalizing internal words while starting with a lowercase letter.
