* <p>For best interoperability and performance use JSON that complies with
* RFC 4627, such as that generated by {@link JSONStringer}. For legacy reasons
* this parser is lenient, so a successful parse does not indicate that the
* input string was valid JSON. All of the following syntax errors will be
* ignored:
* <ul>
* <li>End of line comments starting with {@code //} or {@code #} and ending
* with a newline character.
* <li>C-style comments starting with {@code /*} and ending with
* {@code *}{@code /}. Such comments may not be nested.
* <li>Strings that are unquoted or {@code 'single quoted'}.
* <li>Hexadecimal integers prefixed with {@code 0x} or {@code 0X}.
* <li>Octal integers prefixed with {@code 0}.
* <li>Array elements separated by {@code ;}.
* <li>Unnecessary array separators. These are interpreted as if null was the
* omitted value.
* <li>Key-value pairs separated by {@code =} or {@code =>}.
* <li>Key-value pairs separated by {@code ;}.
* </ul>
*
* <p>Each tokener may be used to parse a single JSON string. Instances of this
* class are not thread safe. Although this class is nonfinal, it was not
* designed for inheritance and should not be subclassed. In particular,

/**
* JSONWriter provides a quick and convenient way of producing JSON text.
* The texts produced strictly conform to JSON syntax rules. No whitespace is
* added, so the results are ready for transmission or storage. Each instance of
* JSONWriter can produce one JSON text.
* <p>
* A JSONWriter instance provides a <code>value</code> method for appending
* values to the
* text, and a <code>key</code>
* method for adding keys before values in objects. There are <code>array</code>
* and <code>endArray</code> methods that make and bound array values, and
* <code>object</code> and <code>endObject</code> methods which make and bound
* object values. All of these methods return the JSONWriter instance,
* permitting a cascade style. For example, <pre>
* new JSONWriter(myWriter)
* .object()
* .key("JSON")
* .value("Hello, World!")
* .endObject();</pre> which writes <pre>
* {"JSON":"Hello, World!"}</pre>
* <p>
* The first method called must be <code>array</code> or <code>object</code>.
* There are no methods for adding commas or colons. JSONWriter adds them for
* you. Objects and arrays can be nested up to 20 levels deep.
* <p>
* This can sometimes be easier than using a JSONObject to build a string.
