# Making it myself, functional programming extensions
# Specification
- soft - Eager evaluation, works like JavaScript built-in function
- hard - Support Iterator/Iterable protocol by Generator
- lazy - Support Lazy evaluation
- concurrency - Support Concurrency processing (Not parallel)
# Iterable protocol
```javascript
const result = go(
[1,2,3,4,5],
filter((a) => a % 2), // [1, 3, 5]
map((a) => a * a), // [1, 9, 25]
reduce(sum),
log // 35
);
// It is possible
go(
[
Promise.resolve(1),
Promise.resolve(2),
Promise.resolve(3),
Promise.resolve(4),
Promise.resolve(5),
],
filter((a) => a % 2),
map((a) => a * a),
take(2),
log // [1,9]
);
```
# Lazy evaluation
- `L` functions can be evaluated lazy
- `L` is namespace for lazy functions
```javascript
go(
range(Infinity),
L.filter((a) => a % 2),
L.map((a) => a * a),
take(2),
log // [1,9]
);
// flow: 1 -> 1 -> 2 -> 3 -> 9 -> log
```
# Concurrency
- `C` functions can be evaluated concurrency.
- `C` is namespace for concurrency functions
```javascript
await map(getData, range(10))
// After 10 seconds
// [data1, data2.. data10]
const data = await C.map(getData, range(10))
// After 1 seconds
// [data1, data2.. data10]
```
