How Do You Call A Function With Parameters In A .then Function In A Javascript Promise String?

I am converting my AWS lambda functions, written in node.js, to use promises instead of callbacks. I'm wrapping all of my functions in the handler with the handler code. I'm tryi

Solution 1:

You can use Promise.all(), .then(), Function.prototype.bind(); returnrp.get() from getData()

returnPromise.all(users.map(function(user) {
   userId = // the value from the user record;        // Request a tokenvar tokenParams = {
       an object of params
     };
   returngetToken(tokenParams)
     .then(getData.bind(null, userId, user.dbName))
     .catch(function(e) {
       console.log("caught an error");
       throw e
     });
 }))

Solution 2:

When using a promise, your code should look more like this.

when.try(() => {
    return api.some_api_call
})
.then((results) => {
    const whatIAmLookingFor = {
        data: results.data
    };

    someFunction(whatIAmLookingFor);
})
.then(() => {
    return api.some_other_api_call
})
.then((results) => {
    const whatIAmLookingFor = {
        data: results.data
    };

    someOtherFunction(whatIAmLookingFor); 
.catch(() => {
    console.log('oh no!');
})
});
