Parameter passing when the first call to next makes no sense to print out any results

function * Read () { 
    the let A = the yield. 1 ; 
    the console.log (A); 
    the let B = 2 the yield ; 
    the console.log (B); 
    the let C = the yield. 3 ; 
    the console.log (C); 
} 
the let IT = Read ( 'A' ); 
it.next (); // parameter passing when the first call to next makes no sense
