-# js_util
-
-[![Build Status](https://travis-ci.org/fluidic/js_util.svg?branch=master)](https://travis-ci.org/fluidic/js_util)
-
-Utilities to access JavaScript from Dart.
-
-* toJS(o): Converts a Dart object to a JavaScript object.
-* newObject(): Creates a new JavaScript object.
-* defineProperty(o, String prop, PropertyDescription desc): A wrapper for [Object.defineProperty][defineProperty]
-* getValue(o, String prop): Returns `o[prop]`.
-* setValue(o, String prop, value): Performs `o[prop] = value`.
-
-These utilities are of great help if a JavaScript API takes a JavaScript object
-with keys that are not fixed because [js][js] package does not let you create a
-JavaScript object without declaring a Dart class with `@JS()` and `@anonymous`.
-
-[defineProperty]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty
-[js]: https://pub.dartlang.org/packages/js
-
-## Getting Started
-
-Include `js_util.js` in index.html to use js_util functions.
-
-```html
-<html>
- <head>
- <script async src="packages/js_util/dist/js_util.js"></script>
- <script async src="packages/browser/dart.js"></script>
- </head>
-</html>
-```
-
-## Usage
-
-A simple usage example:
-
-```dart
-final obj = newObject();
-defineProperty(obj, 'foo', new PropertyDescription(enumerable: true, value: 1));
-defineProperty(obj, 'bar', new PropertyDescription(enumerable: false, value: 2));
-```
-
-```dart
-final obj = newObject();
-setValue(obj, 'foo', 1);
-setValue(obj, 'bar', 2);
-
-print(getValue(obj, 'foo')); // 1
-print(getValue(obj, 'bar')); // 2
-```
-
-```dart
-final jsObj = toJS({
- 'people': [
- {'firstName': 'Kwang Yul', 'lastName': 'Seo'},
- {'firstName': 'DoHyung', 'lastName': 'Kim'},
- {'firstName': 'Kyusun', 'lastName': 'Kim'}
- ]
-});
-
-final people = getValue(jsObj, 'people');
-print(getValue(people[0], 'firstName')); // 'Kwang Yul'
-```
