// or = new $.Deferred() etc. | // using a promise constructor
myPromiseFn(param+1) | myPromiseFn(param+1)
.then(function(val) { /* or .done */ | .then(function(val) {
d.resolve(val); | resolve(val);
}).catch(function(err) { /* .fail */ | }).catch(function(err) {
d.reject(err); | reject(err);
}); | });
return d.promise; /* or promise() */ | });
} | }
