require spacing around infix operators (space-infix-ops)

要求中缀操作符周围有空格 (space-infix-ops)

The --fix option on the command line can automatically fix some of the problems reported by this rule.

命令行中的 --fix 选项可以自动修复一些该规则报告的问题。

While formatting preferences are very personal, a number of style guides require spaces around operators, such as:

虽然格式化首选项都非常个人化，但大量的风格指南要求运算符周围有空格，例如：

var sum = 1 + 2;

The proponents of these extra spaces believe it make the code easier to read and can more easily highlight potential errors, such as:

这些额外空格的支持者认为它将使代码易于阅读，可以更轻易地突出潜在的错误，例如：

var sum = i+++2;

While this is valid JavaScript syntax, it is hard to determine what the author intended.

虽然这是有效的 JavaScript 语法，但很难确定作者的意图。

This rule is aimed at ensuring there are spaces around infix operators.

此规则旨在确保中缀运算符周围有空格。

This rule accepts a single options argument with the following defaults:

该规则接收唯一一个可选项参数，具有以下默认值：

"space-infix-ops": ["error", {"int32Hint": false}]

Set the int32Hint option to true (default is false) to allow write a|0 without space.

设置 int32Hint 选项为 true (默认 false) 允许 a|0 不带空格.

var foo = bar|0; // `foo` is forced to be signed 32 bit integer

Examples of incorrect code for this rule:

错误代码示例：

/*eslint space-infix-ops: "error"*/
/*eslint-env es6*/

a+b

a+ b

a +b

a?b:c

const a={b:1};

var {a=0}=bar;

function foo(a=0) { }

Examples of correct code for this rule:

正确代码示例：

/*eslint space-infix-ops: "error"*/
/*eslint-env es6*/

a + b

a       + b

a ? b : c

const a = {b:1};

var {a = 0} = bar;

function foo(a = 0) { }

You can turn this rule off if you are not concerned with the consistency of spacing around infix operators.

如果不关心中缀运算符前后间距的一致性，可以关闭此规则。

This rule was introduced in ESLint 0.2.0.
