Options	Content	Value	Error message
Bitwise	Disable bitwise operators (such as ^,&)	Setting: TRUE; Do not set: false	Unexpected use of '??? '. (When set to true)
Curly	Use {} In statements such as if and while for explicit code blocks	Setting: TRUE; Do not set: false	Expected ' {' and instead saw '??? '.
Eqeqeq	Use = = = and!== instead = = and! =	Setting: TRUE; Do not set: false	Use ' = = = ' to compare with ' null '.
Forin	Use Object.prototype.hasOwnProperty () in a for In loop to filter properties in the prototype chain	Setting: TRUE; Do not set: false	The body of a for in should is wrapped in an if statement to filter unwanted properties from the prototype
Immed	Anonymous function calls must be (function() { // body }()); Instead of (function() { // body})(); 这是为了表明，表达式的值是函数的结果，而不是函数本身。	Setting: TRUE; Do not set: false	Move the invocation into the parens that contain the function. ? Wrap an immediate function invocation in parentheses to assist the reader in understanding that the expression is the ResU Lt of a function, and not the function itself.
Latedef	Prohibit use before variable definition	Setting: TRUE; Do not set: false	"Was??? Used before it was defined.
Newcap	The first letter of the constructor name must be capitalized	Setting: TRUE; Do not set: false	A constructor name should start with the uppercase letter.
Noarg	Prohibit the use of Arguments.caller and Arguments.callee	Setting: TRUE; Do not set: false	Avoid Arguments.callee.
Noempty	Suppress empty blocks of code	Setting: TRUE; Do not set: false	Empty block.

Undef	Disallow use of undefined variables that are not in the global variable list	Setting: TRUE; Do not set: false	'??? ' is not defined.
Strict	Strict mode for forcing the use of ES5	Setting: TRUE; Do not set: false	Missing "use strict" statement.
Freeze	Disallow the prototype of a replicated native object (such as array, Date) /* jshint freeze:true */Array.prototype.count = function (value) { return 4; };// -> Warning: Extending prototype of native object: ‘Array‘.	Setting: TRUE; Do not set: false	Warning: Extending prototype of native object: ‘Array‘.
Asi	Allow omitting semicolons	Allow: true; Not allowed: false	Missing semicolon.
Boss	Allows assignment in if,for,while statements; using assignments in conditional statements is often a clerical error if (A = 10) {}	Allow: true; Not allowed: false	Expected a conditional expression and instead saw an assignment.
Debug	Allow debugger statements	Allow: true; Not allowed: false	All ' debugger ' statements should is removed.
Eqnull	Allow ==null ==null is usually used to compare = = = null;=== undefined	Allow: true; Not allowed: false	Use ' = = = ' to compare with ' ~ '.
Evil	Allow use of eval	Allow: true; Not allowed: false	Eval is evil.
Expr	Allow expressions to be used where assignments or function calls should occur	Allow: true; Not allowed: false	Expected an assignment or function call and instead saw an expression.
Iterator	Allow __iterator__; not all browsers support __iterator__.	Allow: true; Not allowed: false	__iterator__ ' is only available in JavaScript 1.7.
Lastsemic	Allow single-line control blocks to omit semicolons var name = (function() { return ‘Anton‘ }());	Allow: true; Not allowed: false	Missing semicolon.
Laxbreak	Allow unsafe line interrupts (used with Laxcomma)	Allow: true; Not allowed: false	Bad line breaking before ' ~ '.
Laxcomma	Allow encoding style to begin with a comma	Allow: true; Not allowed: false	Comma warnings can be turned off with ' Laxcomma '.
Loopfunc	Allow functions to be defined in loops	Allow: true; Not allowed: false	Don ' t make functions within a loop.
Onecase	Allow a switch statement with only one case condition	Allow: true; Not allowed: false	This ' switch ' should is an ' if '.
Proto	Allow Proto (not all browsers support __proto__.)	Allow: true; Not allowed: false	The ' __proto__ ' is deprecated. Against
Regexdash	To understand---"seems to understand that: In the control statement of the regular expression, the beginning of the hyphen or the end of the square brackets-the existence of the tolerance.	Allow: true; Not allowed: false	unescaped '-'.
Scripturl		Allow: true; Not allowed: false
Shadow	Allow variable Shadow function test() { var x = 10; if (true) { var x = 20; } return x;} Based on the function scope, there is no difference between defining variables and defining a single definition multiple times, but it can cause dyslexia.	Allow: true; Not allowed: false	'??? ' is already defined.
Sub	Allow person[' name '] Jshint recommend using Person.name instead of person[' name ']	Allow: true; Not allowed: false	[‘???‘] is better written in dot notation.
Supernew	Allow new function () {...} and new Object;	Allow: true; Not allowed: false	Weird construction. Delete
Validthis	Allows the use of this in non-constructors in strict mode	Allow: true; Not allowed: false	Possible strict violation.
