Detect a function can be optimized or not.
Original tools come from [Optimization killers](https://github.com/petkaantonov/bluebird/wiki/Optimization-killers)
## Install
```bash
$ npm install optimized --save-dev
```
## Usage
`test.js`:
```js
var optimized = require('optimized');
function defaultArgsReassign(a, b) {
if (arguments.length < 2) b = 5;
}
function reAssignParam(a, b) {
if (b === void 0) b = 5;
}
// optimized(fn, args, ctx) => true / false
optimized(defaultArgsReassign, [1, 2]);
optimized(reAssignParam);
```
Run it with `--allow-natives-syntax --trace_opt --trace_deopt`:
```bash
$ node --allow-natives-syntax --trace_opt --trace_deopt test.js
Function defaultArgsReassign is not optimized
Function reAssignParam is optimized
```
## Test
```bash
$ npm install
$ npm test
```
