    What does ".then" mean in JavaScript?

    Consider this snippet of code:


    return ajaxService.request('post', 'api/{ticketId}/alt-forms/getSatelliteMapUrl', geoCodedata, { failureMessage: 'Failed to Geocode SatMap/PDF'})
    .then(function (satelliteMapData, data) {

    Is the ".then" comment attached immediately to the previous "return" statement? If so, how? If not, then would the functionality of this JavaScript bit not be impacted if I put an "alert" statement immediately before the ".then" statement and immediately after the "return" statement?

    I suggest you read more about the promise in JavaScript.

    its a then, you should do the math and realize how PEMDAS works or something similar, so you can monitor your codes better, and not lose time.
