 Enjoy 是基于 Java 语言的极轻量极魔板引擎。极轻量级仅 171K 并且不依赖任何第三方。极简设计仅 if、for、switch、set、define、include、render 七个核心指令，让学习成本低到极致。独创 DKFF(Dynamic Key Feature Forward) 词法分析算法与 DLRD (Double Layer Recursive Descent)语法分析算法，避免使用 javacc、antlr、jflex 生成器，令代码量少到极致。

 #### Enjoy 主要特点
 - 消灭传统模板引擎中大量繁杂概念，仅七个核心指令，学习成本极低
 - 独创 DKFF 词法分析算法与 DLRD 语法分析算法，避免使用 javacc、antlr
-- 功能强大，极为简单覆盖掉 freemarker、velocity 的核心功能
-- 扩展性强，支持多种扩展方式，且是唯一支持指令级扩展的模板引擎
 - 与 java 打通式设计，在模板中与 java 交互极为方便
 - 贴近 java 使用直觉，为 java 开发者量身打造
+- 功能强大，极为简单覆盖掉 freemarker、velocity 的核心功能
