max-statements-per-line
强制执行每行允许的最大语句数
This rule was deprecated in ESLint v8.53.0. Please use the corresponding rule in @stylistic/eslint-plugin.
包含太多语句的代码行可能难以阅读。代码通常是自上而下阅读的，尤其是在扫描时，因此限制单行允许的语句数量对可读性和可维护性非常有益。
¥A line of code containing too many statements can be difficult to read. Code is generally read from the top down, especially when scanning, so limiting the number of statements allowed on a single line can be very beneficial for readability and maintainability.
function foo () { var bar; if (condition) { bar = 1; } else { bar = 2; } return true; } // too many statements

/*eslint max-statements-per-line: ["error", { "max": 1 }]*/
var bar; var baz;
if (condition) { bar = 1; }
for (var i = 0; i < length; ++i) { bar = 1; }
switch (discriminant) { default: break; }
function foo() { bar = 1; }
var qux = function qux() { bar = 1; };
(function foo() { bar = 1; })();
使用默认 { "max": 1 } 选项的此规则的正确代码示例：

/*eslint max-statements-per-line: ["error", { "max": 1 }]*/
var bar, baz;
if (condition) bar = 1;
for (var i = 0; i < length; ++i);
switch (discriminant) { default: }
function foo() { }
var qux = function qux() { };
(function foo() { })();
使用 { "max": 2 } 选项的此规则的错误代码示例：
¥Examples of incorrect code for this rule with the { "max": 2 } option:
/*eslint max-statements-per-line: ["error", { "max": 2 }]*/
var bar; var baz; var qux;
if (condition) { bar = 1; } else { baz = 2; }
for (var i = 0; i < length; ++i) { bar = 1; baz = 2; }
switch (discriminant) { case 'test': break; default: break; }
function foo() { bar = 1; baz = 2; }
var qux = function qux() { bar = 1; baz = 2; };
(function foo() { bar = 1; baz = 2; })();
使用 { "max": 2 } 选项的此规则的正确代码示例：
¥Examples of correct code for this rule with the { "max": 2 } option:
/*eslint max-statements-per-line: ["error", { "max": 2 }]*/
var bar; var baz;
if (condition) bar = 1; if (condition) baz = 2;
for (var i = 0; i < length; ++i) { bar = 1; }
switch (discriminant) { default: break; }
