space-infix-ops

要求中缀运算符周围有间距

此规则在 ESLint v8.53.0 中已弃用。请在 @stylistic/eslint-plugin-js 中使用 相应的规则。

¥This rule was deprecated in ESLint v8.53.0. Please use the corresponding rule in @stylistic/eslint-plugin-js.

虽然格式偏好是非常个人化的，但许多风格指南需要在运算符周围留有空格，例如：

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

var sum = 1 + 2;
1

该规则的支持者认为，它使代码更易于阅读，并且可以更轻松地突出潜在错误，例如：

¥Proponents of this rule believe that it makes code easier to read and can more easily highlight potential errors, such as:

var sum = i+++2;
1

虽然这是有效的 JavaScript 语法，但很难确定作者的意图。

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

选项

¥Options

此规则接受具有以下默认值的单个选项参数：

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

int32Hint

将 int32Hint 选项设置为 true（默认为 false）以允许在没有空格的情况下写入 a|0。

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

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