no-extra-semi

禁止不必要的分号

关于分号需求位置的打字错误和误解可能会导致不必要的分号。虽然从技术上讲这不是错误，但多余的分号在阅读代码时可能会引起混淆。

🌐 Typing mistakes and misunderstandings about where semicolons are required can lead to semicolons that are unnecessary. While not technically an error, extra semicolons can cause confusion when reading code.

规则详情

🌐 Rule Details

此规则不允许不必要的分号。

🌐 This rule disallows unnecessary semicolons.

此规则报告的问题可以自动修复，除非删除分号会导致后续语句变为指令，例如 "use strict"。

🌐 Problems reported by this rule can be fixed automatically, except when removing a semicolon would cause a following statement to become a directive such as "use strict".

此规则的错误代码示例：

🌐 Examples of incorrect code for this rule:

/*eslint no-extra-semi: "error"*/

var x = 5;;

function foo() {
    // code
};

class C {
    field;;

    method() {
        // code
    };

    static {
        // code
    };
};
