Common Questions

Frequently Asked Questions

What is 'Sentence case'?

Sentence case capitalizes the first letter of each sentence and converts the rest to lower case. It's the standard casing for most written English prose.

How does 'Title Case' work?

Title Case capitalizes the first letter of major words while keeping minor words (like 'a', 'an', 'the', 'in') in lower case, making it perfect for headlines.

When should I use camelCase vs snake_case?

camelCase (e.g., myVariable) is standard in JavaScript and Java. snake_case (e.g., my_variable) is preferred in Python and database column names.

What is a URL Slug?

A URL Slug creates a web-friendly version of your text by lowercase all letters, removing special characters, and replacing spaces with hyphens (e.g., "Hello World!" becomes "hello-world").
