Trying to get an array of view coordinates

[ [55.75, 37.50], [55.75, 37.71], [55.70, 37.70] ]

Code

 var coords = []; for ( var i = 0; i < addresses.length; i++ ) { ymaps.geocode(addresses[i], {results: 1 }).then(function (res) { console.log(res.geoObjects.get(0).geometry.getCoordinates()); // ok coords.push(res.geoObjects.get(0).geometry.getCoordinates()); }); } console.log(coords); // empty

At the output, I get an empty array: (

  • Because console.log(coords); runs before geocode calls complete. Read about asynchrony and promises - Alexey Ten
  • Yes, I read already. If I knew how to solve this problem, I would not write here, it is logical? So your answer is at least incorrect. - Guest
  • This question is asked several times a week. ru.stackoverflow.com/a/487996/190728 here, for example, one of the solutions to your problem. - Alexey Ten
  • Well, thanks and on it. The truth is not quite clear how this. Stackoverflow.com/questions/487992 ... can help solve my problem. - Guest
