• (string) The camelized string.

Example:

"active_record".camelize(2); // "ActiveRecord"
"post_category".camelize(true); // "postCategory"

Function String Classify

Create a class name from a plural table name like Rails does for table names to models. Note that this returns a string and not a Class.

Syntax:

str.classify();

"egg_and_hams".classify(); // "EggAndHam"
