@typescript-eslint/prefer-includes
==================================

强制使用“includes”方法而不是“indexOf”方法。

#### 规则配置

// code-linter.json5
{
  "rules": {
    "@typescript-eslint/prefer-includes": "error"
  }
}

#### 选项

该规则无需配置额外选项。

#### 正例

const str: string = 'hello';
const array: string\[\] = \['hello'\];
const readonlyArray: readonly string\[\] = \['hello'\];

str.includes('h');
array.includes('h');
readonlyArray.includes('h');

#### 反例

const str: string = 'hello';
const array: string\[\] = \['hello'\];
const readonlyArray: readonly string\[\] = \['hello'\];

const num = -1;
let vv = str.indexOf('h') !== num;
vv = vv && array.indexOf('h') !== num;
vv = vv && readonlyArray.indexOf('h') !== num;
export { vv };
