Interesting History
The evolution of letter case conventions has a fascinating history dating back to the 8th century. The distinction between upper and lower case letters emerged from medieval manuscript traditions, where scribes developed different letter forms for different purposes. The advent of printing in the 15th century standardized these cases, but it wasn't until the rise of computing in the 20th century that new case conventions emerged. Programming languages introduced camelCase and PascalCase in the 1970s, while snake_case gained popularity with Unix systems. Today, different case styles serve specific purposes in programming, typography, and digital communication, making case conversion tools essential in modern text processing.
