Frequently asked questions
When to use camelCase vs snake_case?
JavaScript/Java/C++: camelCase (myVariable). Python/Ruby/database columns: snake_case (my_variable). CSS/URLs: kebab-case (my-variable). Constants: CONSTANT_CASE (MY_CONSTANT).
Difference between camel and Pascal?
camelCase starts lowercase (myVariable). PascalCase starts uppercase (MyClass). PascalCase typically for class names, camelCase for variables and functions.
Sentence vs Title case?
Sentence: only first letter capitalized (Hello world). Title: every important word capitalized (Hello World). Title case is used in headlines and book titles.
