What is $timeout used for here?

Question

Angular

I understand someone else's code and it is not clear why $timeout is used here?

_initThreadId() {
      const me = this;
      me.threadId = this.dialogs[0].threadId || me.dialogs[0].code;
      me.$timeout(function () {
        if (me._comeFromFooter()) me.threadId = _.find(me.dialogs, d => d.employeeType === me.employeeType).threadId;
        if (me._comeFromRepresentatives()) me.threadId = _.find(me.dialogs, d => d.employeeType === 'CLIENT_MANAGER').threadId;
      });
    }

    _comeFromRepresentatives() {
      return angular.isDefined(this.currentUserRepresentative);
    }

    _comeFromFooter() {
      return angular.isDefined(this.employeeType);
    }

It is also not clear why only the _comeFromRepresentatives function works, but does not enter _comeFromFooter().

Answer 1

Read why they use the setTimeout(function, 0) technique at all. And perhaps this will give you an answer why exactly in this case they use timeout
