```
* take:
```js

.take(2); // [1, 2]
```
* sum:
```js
va([{ a: 1 }, { a: 2 }, { a: 3 }])
.sum(function (i) { return i.a; }); // 6
```
* select:
```js
va([{ a: 1 }, { a: 2 }, { a: 3 }])
.select(function (i) { return i.a; }) // [1, 2, 3]
```
* selectMany:
```js
va([{ a: [1, 2] }, { a: [3] }, { a: [4, 5, 6] }])
.selectMany(function (i) { return i.a; }) // [1, 2, 3, 4, 5, 6]
```
* contains:
```js
va([1, 2, 3])
.contains(1); // true
```
* all:
```js
va([1, 2, 3])
.all(function (i) { return i > 0; }); // true
```
* any:
```js
va([1, 2, 3])
.any(function (i) { return i > 2; }); // true
```
* where:
```js
va([1, 2, 3])
.where(function (i) { return i > 2; }); // [3]
```
* first:
```js
va([1, 2, 3])
.first(function (i) { return i > 1; }); // [2]
```
* last:
```js
va([1, 2, 3])
.last(); // 3
```
* distinct:
```js
va([1, 1, 2, 3, 3])
.distinct(); // [1, 2, 3]
```
* groupBy:
```js
va([{ a: 1 }, { a: 1 }, { a: 2 }, { a: 3 }])
.groupBy(function (i) { return i.a; }); //Array[2], Array[1], Array[1]
```
* orderBy:
```js
va([{ a: 2 }, { a: 1 }, { a: 3 }])
.orderBy(function (i) { return i.a; }); // [{ a: 1 }, { a: 2 }, { a: 3 }]
```
* orderByDescending:
```js
va([{ a: 1 }, { a: 2 }, { a: 3 }])
.orderByDescending(function (i) { return i.a; }); // [{ a: 3 }, { a: 2 }, { a: 1 }]
```
* forEach:
```js
va([1, 2, 3])
.forEach(function (item, index) { console.log(item) }); // 1, 2, 3
