+ JSHINT is a global function. It takes two parameters.
+
+ var myResult = JSHINT(source, option);
+
+ The first parameter is either a string or an array of strings. If it is a
+ string, it will be split on '\n' or '\r'. If it is an array of strings, it
+ is assumed that each string represents one line. The source can be a
+ JavaScript text or a JSON text.
+
+ The second parameter is an optional object of options which control the
+ operation of JSHINT. Most of the options are booleans: They are all
+ optional and have a default value of false. One of the options, predef,
+ can be an array of names, which will be used to declare global variables,
+ or an object whose keys are used as global names, with a boolean value
+ that determines if they are assignable.
+
+ If it checks out, JSHINT returns true. Otherwise, it returns false.
+
+ If false, you can inspect JSHINT.errors to find out the problems.
+ JSHINT.errors is an array of objects containing these members:
+
+ {
+ line : The line (relative to 0) at which the lint was found
+ character : The character (relative to 0) at which the lint was found
+ reason : The problem
+ evidence : The text line in which the problem occurred
+ raw : The raw message before the details were inserted
+ a : The first detail
+ b : The second detail
+ c : The third detail
+ d : The fourth detail
+ }
+
+ If a fatal error was found, a null will be the last element of the
+ JSHINT.errors array.
+
+ You can request a Function Report, which shows all of the functions
+ and the parameters and vars that they use. This can be used to find
+ implied global variables and other problems. The report is in HTML and
+ can be inserted in an HTML <body>.
+
+ var myReport = JSHINT.report(limited);
+
+ If limited is true, then the report will be limited to only errors.
+
+ You can request a data structure which contains JSHint's results.
+
+ var myData = JSHINT.data();
+
+ It returns a structure with this form:
+
+ {
+ errors: [
+ {
+ line: NUMBER,
+ character: NUMBER,
+ reason: STRING,
+ evidence: STRING
+ }
+ ],
+ functions: [
+ name: STRING,
