## Additional code styles
### Use ES6 Object Destructing

Please use Object Destructing whenever it's possible.

**Example**: Importing from library

```js

// BAD
import Code from 'library'
const subCode = Code.subCode
subCode()

// GOOD
import { subCode } from 'library'
subCode()
```

**Example**: Extract data from react component state

```
// BAD
<h1>{this.state.name}</h1>

// GOOD
const { name } = this.state
<h1>{name}</h1>
```

### Use meaningful name
This is actually not a "code style" but rather a requirement in every projects. Please name your variables carefully.

**Example**: Naming callback function for event

```js
// BAD
<h1 onclick={onClick}>Name</h1>

// GOOD
<h1 onclick={onNameClick}>Name</h1>
```

### Don't write long conditional statement
When writing a conditional statement, if it's too long, cut it into small meaningful variables.

```js
// BAD
if (note.type == 'markdown' && note.index == 2 && note.content.indexOf('string') != -1)

// GOOD
const isSecondMarkdownNote = note.type == 'markdown' && note.index == 2
const isNoteHasString = note.content.indexOf('string') != -1
if (isSecondMarkdownNote && isNoteHasString)
```
