ES7 - Optimization of promise

Optimize Promise

stay es6 Optimization based on

grammar

key word :async

// key word  async  Return value Promise object 
        async function task1(){
    
            return 'task1 ... Successful implementation ';
        }

The return value is Promise object

simplify then()

key word :await

notes : Use await There has to be async Modify function

Example

 async function task2(){
    
            return 'task2 ... Successful implementation ';
        }
 async function task3(){
    
            return 'task3 ... Successful implementation ';
       	}
        //es7 await  simplify  then()  notes : Use await There has to be async Modify function 
        async function test(){
    
            let ret1=await task1();
            console.log('es7-->'+ret1);
            let ret2=await task2();
            console.log('es7-->'+ret2);
            let ret3=await task3();
            console.log('es7-->'+ret3);
        }
        test();    

Es7 Yes Promise The optimization of is completed by practice
