Converts HTML special characters to their entity equivalents. |
8. | evalJSON()

9. | evalScripts()
Evaluates the content of any script block present in the string. Returns an array containing the value returned by each script. |

Returns a debug-oriented version of the string. |
14. | interpolate()
Treats the string as a Template and fills it with object’s properties. |
15. | isJSON()
Checks if the string is valid JSON by the use of regular expressions. This security method is called internally. |
16. | parseQuery()
Parses a URI-like query string and returns an object composed of parameter/value pairs. |
17. | scan()
Allows iterating over every occurrence of the given pattern. |
18. | startsWith()
Checks if the string starts with substring. |
19. | strip()
Strips all the leading and trailing whitespace from a string. |

22. | 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. |

Used internally by ObjectRange. Converts the last character of the string to the following character in the Unicode alphabet. |
24. | times()
Concatenates the string count times. |
25. | toArray()
Splits the string character-by-character and returns an array with the result. |
26. | toJSON()

27. | toQueryParams()
Parses a URI-like query string and returns an object composed of parameter/value pairs. |
28. | truncate()
Truncates a string to the given length and appends a suffix to it (indicating that it is only an excerpt). |
29. | underscore()
Converts a camelized string into a series of words separated by an underscore (“_”). |
