i need to use one promise to retrieve some data before continue with the logical of my code.

The thing ins i try to use this:

if (label === 'edit') {
    new skill_watson_export_no_append(jsonSkillIntentsUpdate, id_skill_tst).update_skill_no_append(jsonSkillIntentsUpdate, id_skill_tst)
} else {
    new skill_watson_export(new_intent_preprocess, id_skill_tst).update_skill_append(new_intent_preprocess, id_skill_tst)
}.then(response_watson => {

but i have an error 'Declaration or statment expected'

i need to use one of this promises before continue, if not the only way is to repeat 200 lines of code. Someone help me....? thanks

if statements don't provide a value when they are evaluated. You can't follow on with a method call.

You could use a conditional operator:

(
    (label === 'edit') ?
        new skill_watson_export_no_append(jsonSkillIntentsUpdate, id_skill_tst).update_skill_no_append(jsonSkillIntentsUpdate, id_skill_tst) :
        new skill_watson_export(new_intent_preprocess, id_skill_tst).update_skill_append(new_intent_preprocess, id_skill_tst)
).then( ... )

But, frankly, that is rather unwieldy, and assigning the promise to a variable declared with let would probably be easier to manage.

Breaking the logic out into its own function that returns the apropriate promise would likely be even easier to maintain.
