Javascript promise won't resolve before exiting funciton

I am attempting to get the current session in javascript. The issue I am running into is the Promise will not resolve unless I am debugging and use a breakpoint. Here is my code (NOTE: placing a breakpoint at “return values” causes the promise to populate the values object EVERY TIME. Without the breakpoint the object NEVER gets populated.)

function GetSession(authClient, i) {

      var values = { userId: '', sessionId: ''};
      
      authClient.session.get()
        .then(result => {
          values.userId = result.userId;
          values.sessionId = result.id;
        }).catch(err => alert(err));

      return values;
    }

Anyone have any ideas?

You need to read up on how Promises work in Javascript

Try https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise

There’s two ways to get what you are looking for - first to to have the function return a Promise

function GetSession(authClient, i) {
      return new Promise(
           (cb, err) => {
               var values = { userId: '', sessionId: ''};
               authClient.session.get()
                   .then(result => {
                       values.userId = result.userId;
                       values.sessionId = result.id;
                       cb(values)
                    })
                   .catch(e => {
                        alert(e)
                        err(e)
                    });
            }
        )
    }

Otherwise turn GetSession into an async function

async function GetSession(authClient, i) {

      var values = { userId: '', sessionId: ''};
      try{
          let result = await authClient.session.get()
          values.userId = result.userId;
          values.sessionId = result.id;
           return values;
        }catch(err){
            alert(err));
        }
    }
