ReactComponentEnvironment.processChildrenUpdates(
    inst,
    updateQueue,
  );
}
var setChildrenForInstrumentation = emptyFunction;
if (__DEV__) {

    if (!inst._debugID) {

  setChildrenForInstrumentation = function(children) {
    var debugID = getDebugID(this);
    
    
    if (debugID !== 0) {
      ReactInstrumentation.debugTool.onSetChildren(
        debugID,
