no-unused-expressions

Disallow unused expressions.


此规则扩展了基本 eslint/no-unused-expressions 规则。 它添加了对可选调用表达式 x?.() 和模块声明中的指令的支持。

英：This rule extends the base eslint/no-unused-expressions rule. It adds support for optional call expressions x?.(), and directive in module declarations.

如何使用​

.eslintrc.cjs
module.exports = {
  "rules": {
    // Note: you must disable the base rule as it can report incorrect errors
    "no-unused-expressions": "off",
    "@typescript-eslint/no-unused-expressions": "error"
  }
};
