javascript - Why my promise cant resolve? -

i have got 2 promises. 1 not being resolved , dont know why.

processtradeoffer: chain of promises tries procced object called 'offer'. identifyoffer return var "valida" | "aceptable" | "denegable". if 'valida' need identify items offer. need async function identifyitems(offer) return var 'offerstate' "denegable" | "aceptable" , can decline or accept offer.

i know problem there not in statement (offerstate == 'valida'). code:

const processtradeoffer = function(offer) {     return new promise(function(resolve, reject) {         identyoffer(offer)             .then(function(offerstate) {                 return finishtradeoffer(offer, offerstate);             }).then(function() {                 console.log('aqui');                 return resolve();             })     }) } const finishtradeoffer = function(offer, offerstate) {      return new promise(function(resolve, reject) {         if (offerstate == 'aceptable') {             accepttradeoffer(offer).then(function() {                 return resolve();             })         } else if (offerstate == 'denegable') {             declinetradeoffer(offer).then(function() {                 console.log('here');                 return resolve();             })         } else if (offerstate == 'valida') {             identifyitems(offer).then(function(offerstate) {                 finishtradeoffer(offer, offerstate);             })         }     }) } 

console.log('here') fired succesfully , console.log('aqui') dont.

please write code follows.

const processtradeoffer = function(offer) {   const result = identyoffer(offer)     .then(offerstate => finishtradeoffer(offer, offerstate))    result.then(() =>  console.log('aqui'));    return result;  };  const finishtradeoffer = function(offer, offerstate) {   switch(offerstate) {     case 'aceptable': return accepttradeoffer(offer);      case 'denegable': {       const result = declinetradeoffer(offer);       result.then(() => console.log('here'));       return result;      case 'valida':       return identifyitems(offer)         .then(offerstate => finishtradeoffer(offer, offerstate));      default:        throw "invalid value offerstate!!";   } }; 

the basic point handle case of valida in such way promise resolves. in addition, we've gotten rid of "explicit promise constructor anti-pattern".
