ES6——generator

generator function generator

• Ordinary function, all the way in the end

• generator function, you can stop the middle, where it stopped, with the yield cooperate, to hand over executive power

• yield to give up, give in, meaning abdication

• Need to call the next () method to start the implementation, we need to meet yield stop, kick kick go one step further

• plus a generator function front *sides can have spaces, or near or functionfunction

• Behind the actual generation of multiple small functions to achieve stop and go

  function Show () { 
      the console.log ( 'A' ) 
      the console.log ( 'B' ) 
  } 
  Show () // normal function 
  
  function * Show2 () { 
      the console.log ( '. 1' ) 
      the yield 
      the console.log ( '2 ' ) 
  } 
  the let genObj = Show2 () 
  genObj.next () // . 1 
  genObj.next () // 2 
  genObj.next () // Finally, no result
