eslint/no-useless-concat Suspicious

🚧 An auto-fix is planned for this rule, but not implemented at this time.

禁止对字面量或模板字面量进行不必要的拼接。

当两个字符串可以合并为一个单一字面量时，将它们拼接在一起是没有必要的。

此规则的错误代码示例：

javascript

var foo = "a" + "b";

javascript

var foo = "a" + "b" + "c";

此规则的正确代码示例：

javascript

var foo = "a" + bar;

// 当字符串拼接为多行时
var foo = "a" + "b" + "c";

如何使用

To enable this rule using the config file or in the CLI, you can use:

Config (.oxlintrc.json)Config (oxlint.config.ts)CLI

json

{
  "rules": {
    "no-useless-concat": "error"
  }
}

import { defineConfig } from "oxlint";

export default defineConfig({
  rules: {
    "no-useless-concat": "error",
  },
});

bash

oxlint --deny no-useless-concat

此规则于 v0.4.2 中添加。
