# base example
```js
const assert = require('assert');
const co = require('co');
const BlockRun = require('block-run');

//Promise 
BlockRun.run('testChannel1',()=>{
    return 1;
}).then((res)=>{
    assert.equal(res,1,'Promise failed');
}).catch((e)=>{
    throw e;
});


let p1 =(index,time)=>{
    return new Promise((res,rej)=>{
        setTimeout(()=>{
            res(index);
        },time)
    });
}

// testChannel2 make two async function in sequence 

//co yield 
co(function*(){
    try{
        for(let i = 0;i<10;i++)
        {
            let res = yield BlockRun.run('testChannel2',function* (){
                return yield p1(i,2000);
            });
            assert.equal(res,i,'co yield failed'+res);
        }
    } catch(e)
    {
        throw e;
    }
});

//async
(async () =>{
    try{
        for(let i = 0;i<10;i++)
        {
            let res = await BlockRun.run('testChannel3',async ()=>{
                return await p1(i,2000);
            });
            assert.equal(res,i,'async failed'+res);
        }
    } catch(e)

### code:
```js
let p1 =(index,time)=>{

       {
            console.log(await p1(i,1000))
       }
})();
```
### result:
```
one seconds two number 
two async function run at the same time
```

           });
		console.log(res)
       }
})();
```
### result:
```
one seconds one number 
two async function run in sequence by same channel name
```
