It takes two parameters. + +// var myResult = JSLINT(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 HTML text, or a JSON text, or a CSS text. + +// The second parameter is an optional object of options that control the +// operation of JSLINT. 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, JSLINT returns true. Otherwise, it returns false. + +// If false, you can inspect JSLINT.errors to find out the problems. +// JSLINT.errors is an array of objects containing these properties: + +// { +// 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 stopping error was found, a null will be the last element of the +// JSLINT.errors array. A stopping error means that JSLint was not confident +// enough to continue. It does not necessarily mean that the error was +// especially heinous. + +// 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 . + +// var myReport = JSLINT.report(errors_only); + +// If errors_only is true, then the report will be limited to only errors. + +// You can request a data structure that contains JSLint's results. + +// var myData = JSLINT.data(); + +// It returns a structure with this form: + +// { +// errors: [ +// { +// line: NUMBER, +// character: NUMBER, +// reason: STRING, +// evidence: STRING +// } +// ], +// functions: [ +// { +// name: STRING, +// line: NUMBER, +// last: NUMBER, +// params: [ +// { +// string: STRING +// } +// ], +// closure: [ +// STRING +// ], +// var: [ +// STRING +// ], +// exception: [ +// STRING +// ], +// outer: [ +// STRING +// ], +// unused: [ +// STRING +// ], +// undef: [ +// STRING +// ], +// global: [ +// STRING +// ], +// label: [ +// STRING +// ] +// } +// ], +// globals: [ +// STRING +// ], +// member: { +// STRING: NUMBER +// }, +// urls: [ +// STRING +// ], +// json: BOOLEAN +// } + +// Empty arrays will not be included. + +// You can obtain the parse tree that JSLint constructed while parsing.
