How to make a synchronous loop in meteor? There are get requests in the loop, but they do not have time to be executed, as the loop is already scrolling. How to stop the loop until the get request is completed?

Answer 1

For example, instead of get we will use process.nextTick, which is the same with the callback, just replace it.

var util = require('util');
var j = 0;
function loop() {
  if (++j < 100) {
    console.log(j);
    process.nextTick(loop);
  }
}
process.nextTick(loop);
