## API

### <u>camelCase(text) : string</u>

Converts a string into camel case.

This function trys to split *text* into words with non-alphanumeric characters first. If *text* does not contains non-alphanumeric character, this function trys to split *text* into words before capital letters.

If *text* is a string which is composed of either lower case characters and numerics only (e.g. `abc123`), or upper case characters and numerics only (e.g. `ABC123`), this function regards *text* as one word. (At a result, this function returns a string converted into lower case, e.g. `abc123`).

***NOTE:*** *This function doesn't check data types of the arguments, and assumes that they are given as per the specific data types.*
