驼峰命名法
强制变量名使用 camelCase（驼峰命名法）。
代码库的一致性对于可读性和可维护性至关重要。此规则强制要求您创建的变量声明和对象属性名采用 camelCase（驼峰命名法）。
注意事项
- 变量名允许以
_开头或结尾 - 全大写的变量名（例如常量）可以包含
_ - 如果由于某些原因必须在对象中使用 snake_case（下划线命名法）键，请将其用引号括起来
- 此规则也适用于通过 ES 模块导入或导出的变量，但不适用于这些变量的对象属性

let first_name = "Ichigo";
const obj1 = { last_name: "Hoshimiya" };
const obj2 = { first_name };
const { last_name } = obj1;
function do_something() {}
function foo({ snake_case = "default value" }) {}
class snake_case_class {}
class Also_Not_Valid_Class {}
import { not_camelCased } from "external-module.js";
export * as not_camelCased from "mod.ts";
enum snake_case_enum {
snake_case_variant,

type snake_case_type = { some_property: number };
interface snake_case_interface {
some_property: number;

const obj2 = { "first_name": first_name };
const { last_name: lastName } = obj;
function doSomething() {} // function declarations must be camelCase but...
do_something(); // ...snake_case function calls are allowed
function foo({ snake_case: camelCase = "default value" }) {}
