与 Lodash 兼容性
// es-toolkit/compat 的目标是提供与 lodash 百分之百的功能兼容性
import { chunk } from 'es-toolkit/compat';
chunk([1, 2, 3, 4], 0);
// 返回 [], 与 lodash 完全相同
为了最大限度地兼容 lodash
,请使用 es-toolkit/compat
,这是一个弥合这两个库之间差距的兼容性层。
该模块旨在提供与 lodash
相同的 API,使得在这两个库之间进行切换更加容易。
es-toolkit/compat
已经过 lodash
的实际测试用例进行了全面测试。
需要注意的是,与原始 es-toolkit
相比,es-toolkit/compat
可能会对性能产生轻微影响,并且包大小可能会更大。该模块旨在促进平滑过渡,一旦迁移完成,应替换回原始的 es-toolkit
以获得最佳性能。
设计原则
::: info 设计原则可能会发生变化。 :::
我们的兼容层旨在实现以下功能百分之百的特性一致性:
- 作为 lodash 测试用例编写的功能。
- 可以从
@types/lodash
或@types/lodash-es
的类型推断出的功能。
然而,以下内容不在 es-toolkit/compat
的范围之内:
- 隐式类型转换,例如将空字符串转换为零或假。
- 对特定类型数组有专门实现的函数,比如 sortedUniq。
- 通过 "Seq" 方法支持方法链。
实现状态
::: info 以下表情符号表示每个功能的状态:
- ✅: 已完成
- 📝: 审查中
- ❌: 未实现
值得注意的是,即使某个实现被标记为 "审查中",它可能已经在审查中,以确保与 lodash 的功能百分之百一致,并且可能已经提供相同的功能。 :::
