dasherize()	Replaces every instance of the underscore character ("_") by a dash ("-").
empty()	Checks if the string is empty.
endsWith()	Checks if the string ends with substring.
escapeHTML()	Converts HTML special characters to their entity equivalents.
evalJSON()	Evaluates the JSON in the string and returns the resulting object.

extractScripts()	Extracts the content of any script block present in the string and returns them as an array of strings.
gsub()	Returns the string with every occurrence of a given pattern replaced by either a regular string, the returned value of a function or a Template string.
include()	Check if the string contains a substring.
inspect()	Returns a debug-oriented version of the string.
interpolate()	Treats the string as a Template and fills it with object's properties.
isJSON()	Check if the string is valid JSON by the use of regular expressions. This security method is called internally.
parseQuery()	Parses a URI-like query string and returns an object composed of parameter/value pairs.
scan()	Allows iterating over every occurrence of the given pattern
startsWith()	Checks if the string starts with substring.
strip()	Strips all leading and trailing whitespace from a string.
stripScripts()	Strips a string of anything that looks like an HTML script block.
stripTags()	Strips a string of any HTML tag.
sub()	Returns a string with the first count occurrences of pattern replaced by either a regular string, the returned value of a function or a Template string.
succ()	Used internally by ObjectRange. Converts the last character of the string to the following character in the Unicode alphabet.
times()	Concatenates the string count times.
toArray()	Splits the string character-by-character and returns an array with the result.
toJSON()	Returns a JSON string.
toQueryParams()	Parses a URI-like query string and returns an object composed of parameter/value pairs.
truncate()	Truncates a string to the given length and appends a suffix to it (indicating that it is only an excerpt).
underscore()	Converts a camelized string into a series of words separated by an underscore ("_").
unescapeHTML()	Strips tags and converts the entity forms of special HTML characters to their normal form.
