eslint array-callback-return值无效警告类型错误 是ESLint静态代码分析工具用于检测JavaScript代码中的潜在问题的一种警告类型错误。具体来说,它用于检测数组的遍历方法(如forEach、map、filter等)中的回调函数是否正确返回值。 在JavaScript中,数组的遍历方法通常接受一个回调函数作为参数,并在遍历数组的每个元素时...
要优化这段代码以避免 ESLint 的 array-callback-return 错误,你需要确保 map 函数中的每个回调都返回一个值或者通过早期返回来处理。 在你的例子中,你只在满足特定条件时返回元素。 ESLint 的规则要求每个数组迭代都应有返回值,否则它会抛出警告。 一种解决方案是在不满足任何条件时返回 null 或者使用 filter ...
eslint-disable-next-line array-callback-return 这行代码的作用是在 ESLint 中临时禁用对下一行代码的 array-callback-return 规则的警告。 具体来说,eslint-disable-next-line 是一个 ESLint 提供的注释指令,用于在代码中对特定的 ESLint 规则进行临时禁用。这种禁用通常用于某些特殊情况,当你确信某行代码不违...

1:用Object.keys(this.props.ntn).forEach去替换.map,因为ESLintarray-callback-return这个警告是因为在使用map, filter , reduce没有去返回一个值。 2:当然也可以使用map,在react中用jsx的方式,直接把{}改成()即可。 3:具体参考:https://stackoverflow.com/questions/43685424/expected-to-return-a-value-at...
array-callback-return 在数组方法的回调中强制执行 `return` 语句, `Array` 有几种过滤、映射和折叠的方法。如果我们忘记在这些回调中写 `return` 语句,那可能是一个错误。

since array-callback-return currently checks callbacks for other array functions like map, it would be consistent for ESLint to check the callbacks for forEach. Array#forEach is a commonly used method. should the forEach check be part of array-callback-return or a new rule? The name array...
