-## Usage
-
-### 1. Object.prototype.merge()
-```javascript
-let obj1 = {a: 123, b: 456}
-let obj2 = {a: 22, c: 44}
-let obj3 = {c: 11, e: 55}
-
-o1.merge(o2)
-// now obj1 is {a: 22, b: 456, c: 44}
-// nothing to obj2 
-
-o1.merge(o2, o3)
-// obj1 will be {a: 22, b: 456, c: 11, e: 55}
-// nothing to obj2 & obj3
-
-```
-
-### 2. Object.empty()
-```javascript
-Object.empty({}) // true
-Object.empty({a: 213}) // false
-Object.empty([]) // true
-Object.empty([null]) // false
-Object.empty([undefined]) // false
-
-```
-
-
-### 3. Array.prototype.includes()
-```javascript
-let arr = [1, '3', 54, 32, 'foo']
-
-arr.includes(1) // true
-arr.includes(3) // false
-arr.includes('bar') // false
-arr.includes('54') // false
-
-```
-
-
-### 4. Date.isDate()
-```javascript
-
-Date.isDate(new Date()) // true
-Date.isDate({}) // false
-Date.isDate(['bar']) // false
-Date.isDate('foo') // false
-
-```
-
-
-### 5. Date.prototype.format(format)
-> `format` can be these below:
-> - Y (with century) eg. 1970,2017
-> - y (without century) eg. 70, 117
-> - m month, 01-12
-> - n month, 1-12
-> - d date, 01-31
-> - j date, 1-31
-> - H hours 00-23
-> - h hours 00-12
-> - G hours 0-23
-> - g hours 0-12
-> - i minutes, 00-59
-> - s seconds, 00-59
-> - W how many weeks from 01-01 this year
-> - w how many weeks from 01 this month
-> - D week name, like Mon, Tue, Wed, Thu, Fri, Sat, Sun
-
-```javascript
-
-new Date().format() // default 2017-02-08 12:11:23
-new Date().format('Y-m-d') // 2017-02-08
-new Date().format('Y/n/j') // 2017/2/8
-new Date().format('Y年n月j日 第W周') // 2017年2月10日 第6周
-new Date('Wed Feb 10 2016 23:34:04 GMT+0800 (CST)').format() // 2016-02-10 23:34:04
-new Date('2016-08-10T13:14:44.000Z').format() //2016-08-10 21:14:44
-new Date(1470834884000).format('') //2016-08-10 21:14:44
-
-```
-
-
-### 6. String.prototype.splice(start, len[, fill])
-- start `<Integer>`
-- len `<Integer>`
-- fill `<String>`
-
-```javascript
-let str = 'Hello baby';
-
-str.splice(0, 5) // return  ' baby'
-console.log(str) // nothing tostr, so it return 'Hello baby'
-
-str.splice(0, 5, 'Love') //return 'Love baby'
-
-str.splice(6, 0, 'world, ')// return 'Hello world, baby'
-
-str = str.splice(6) //return  'Holle '
-
-```
-
-
-### 7. String.prototype.htmlspecialchars([sign])
-> Just like php's function - `htmlspecialchars`
-- sign `<String>` (ENT_QUOTES/ENT_NOQUOTES)
-
-```javascript
-let str = `<script>alert('hello world')</script>`
-
-str.htmlspecialchars() // &lt;script&gt;alert('hello world')&lt;/script&gt;
-str.htmlspecialchars('ENT_QUOTES') // &lt;script&gt;alert(&#39;hello world&#39;)&lt;/script&gt;
-
-```
-
-
-### 8. String.prototype.tohtml()
-```javascript
-let str = `&lt;script&gt;alert(&#39;hello world&#39;)&lt;/script&gt;`
-str.tohtml() // <script>alert('hello world')</script>
-
-```
