wkn is easy possible to run the processing to another thread.
# Concept
* Simple API
* No Config
* Light
# Installing
```bash
$ npm install wkn
```
# Example
```javascript
import wkn from 'wkn';
/**
* Takes function and arguments, moves the processing to another thread,
* and receives the processing result on Promise.
* @param {Function} function to have retunrn value. (Be processed in Web Worker context)
* @param {...*} [arguments] arguments
* @returns {Promise} Returns Processing result as Promise
*/
// Simple usage
wkn(arg => arg + 1, 100)
.then((value) => {
console.log(value); // 101
});
// Two arguments
wkn((arg1, arg2) => `${arg1}!${arg2}!`, 'hoge', 'foo')
.then((value) => {
console.log(value); // hoge!foo!
});
// Use moment.js
wkn((years, months, days, hours, minutes, seconds) => {
importScripts('https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.10.6/moment.js');
const m = moment(new Date(years, months, days, hours, minutes, seconds));
return m.hours();
}, 2011, 2, 12, 5, 0, 0)
.then((value) => {
console.log(value); // 5
});
// Heavy processing
wkn(() => {
let num = 0;
for (let i = 0; i < 100000000; i++) {
num += i;
}
return num;
})
.then((value) => {
console.log(value); // 4999999950000000
});
// onRejected
wkn(arg => arg.map(_ => `${_}!`), {})
.then((value) => {
console.log(value); // not fire
}, (reason) => {
console.error(reason); // arg.map is not a functio
});
```
