Functions: String

Kahuna provides the following string manipulation functions, allowing you to work efficiently with text values within your scripts:

Function	Description	Example
`len(str)`	Returns the length of the string `str`	`len("hello")` → `5`
`length(str)`	Alias for `len(str)`	`length("hello")` → `5`
`lower(str)`	Converts `str` to lowercase	`lower("HELLO")` → `"hello"`
`upper(str)`	Converts `str` to uppercase	`upper("hello")` → `"HELLO"`
`concat(left, right)`	Concatenates two strings	`concat("hello ", "world")` → `"hello world"`
`to_json(value)`	Serializes a value to a JSON string	`to_json([1, 2])` → `"[1,2]"`

These functions are useful for formatting values, validating inputs, parsing data, and handling dynamic key names in Kahuna Scripts.
