no-console

禁止使用 console

在设计为在浏览器中执行的 JavaScript 中，避免在 console 上使用方法被认为是最佳实践。此类消息被认为是出于调试目的，因此不适合发送给客户端。一般来说，使用 console 的调用应该在被推送到生产环境之前被剥离。

console.log("Made it here.");
console.error("That shouldn't have happened.");

规则详情

此规则不允许调用或分配 console 对象的方法。

此规则的错误代码示例：

/* eslint no-console: "error" */

console.log("Log a debug level message.");
console.warn("Log a warn level message.");
console.error("Log an error level message.");
console.log = foo();

此规则的正确代码示例：

/* eslint no-console: "error" */

// custom console
Console.log("Hello world!");
