require-yield

Require generator functions to contain yield

Recommended

The "extends": "eslint:recommended" property in a configuration file enables this rule

规则细节

该规则对没有 yield 关键字的生成器函数产生警告。

示例

使用此规则的错误示例:

Open in Playground
/*eslint require-yield: "error"*/
/*eslint-env es6*/

function* foo() {
  return 10;
}

使用此规则的正确示例:

Open in Playground
/*eslint require-yield: "error"*/
/*eslint-env es6*/

function* foo() {
  yield 5;
  return 10;
}

function foo() {
  return 10;
}

// This rule does not warn on empty generator functions.
function* foo() { }

何时不用

如果你不想通知没有 yield 表达的生成器函数,你可以安全地禁用此规则。

Version

This rule was introduced in ESLint v1.0.0-rc-1.
