什么是 JavaScript AST，如何使用它? [英] What is JavaScript AST, how to play with it?

问题描述

抽象语法树..我一直听说在 Github 上编译为 SpiderMonkey AST.
那么，这是 JS 语法树的实际标准吗?还有 V8，V8 是否使用相同类型的 AST?

Abstract Syntax Tree.. I always heard that compile to SpiderMonkey AST on Github.
So, is that a actual standard of JS syntax tree? And there's V8, is V8 using the same kind of AST?

我该怎么玩?

推荐答案

SpiderMonkey 提供了 parser api.这可能是掌握语法对象的最简单方法.

SpiderMonkey offers the parser api. This is probably the easiest way to get your hands on the syntax objects.

还有开放的 js-js 解析器，例如 Esprima(实际上是 ECMAScript，但它就在胡同)

There's also open js-js parsers like Esprima (which is ECMAScript, really, but it's right up the alley)
