1# estree-walker2 3Simple utility for walking an [ESTree](https://github.com/estree/estree)-compliant AST, such as one generated by [acorn](https://github.com/marijnh/acorn).4 5 6## Installation7 8```bash9npm i estree-walker10```11 12 13## Usage14 15```js16var walk = require('estree-walker').walk;17var acorn = require('acorn');18 19ast = acorn.parse(sourceCode, options); // https://github.com/acornjs/acorn20 21walk(ast, {22  enter(node, parent, prop, index) {23    // some code happens24  },25  leave(node, parent, prop, index) {26    // some code happens27  }28});29```30 31Inside the `enter` function, calling `this.skip()` will prevent the node's children being walked, or the `leave` function (which is optional) being called.32 33Call `this.replace(new_node)` in either `enter` or `leave` to replace the current node with a new one.34 35Call `this.remove()` in either `enter` or `leave` to remove the current node.36 37## Why not use estraverse?38 39The ESTree spec is evolving to accommodate ES6/7. I've had a couple of experiences where [estraverse](https://github.com/estools/estraverse) was unable to handle an AST generated by recent versions of acorn, because it hard-codes visitor keys.40 41estree-walker, by contrast, simply enumerates a node's properties to find child nodes (and child lists of nodes), and is therefore resistant to spec changes. It's also much smaller. (The performance, if you're wondering, is basically identical.)42 43None of which should be taken as criticism of estraverse, which has more features and has been battle-tested in many more situations, and for which I'm very grateful.44 45 46## License47 48MIT49
