	# babel-traverse

	> babel-traverse maintains the overall tree state, and is responsible for replacing, removing, and adding nodes.

	## Install

	```sh
	$ npm install --save babel-traverse
	```

	## Usage

	We can use it alongside Babylon to traverse and update nodes:

	```js
	import * as babylon from "babylon";
	import traverse from "babel-traverse";

	const code = `function square(n) {
	return n * n;
	}`;

	const ast = babylon.parse(code);

	traverse(ast, {
	enter(path) {
	if (path.isIdentifier({ name: "n" })) {
	path.node.name = "x";
	}
	}
	});
	```
