babel 的转译过程也分为三个阶段,这三步具体是:
解析 Parse: 将代码解析生成抽象语法树( 即AST ),即词法分析与语法分析的过程 转换 Transform: 对于 AST 进行变换一系列的操作,babel 接受得到 AST 并通过 babel-traverse 对其进行遍历,在此过程中进行添加、更新及移除等操作 生成 Generate: 将变换后的 AST 再转换为 JS 代码, 使用到的模块是 babel-generator

Babel的插件模块需要你暴露一个function,function内返回visitor
module.export = function(babel){ return { visitor:{ } } }
Sorry, something went wrong.
