How to organize animation using snap.svg?

Question

I am trying to animate several objects in a sequence using http://snapsvg.io/ .

I want the first object to move, and after the completion of the second object to move, etc.

Instead of the following code, all animations at once.

    var s = Snap("#svg");

    var triangle = s.path("M200 200,L600,500 L200,500 L200,200");

    var triangleClone = triangle.clone();
    triangleClone.animate({'transform' : 'r90,200,200 T400,300'}, 1000);

    var triangleClone2 = triangle.clone();
    triangleClone2.animate({'transform' : 'r180,200,200 T100,700'},1000);

    var triangleClone3 = triangle.clone();
    triangleClone3.animate({'transform' : 'r270,200,200 T-300,400'},1000);

What approach do you need to control when something comes to life? It seems that there is not one call to connect.

Snap has callback function after animation, according to docs

If you want to do a few sequentially, you can make it a little easier and create a function in which you simply pass arrays of animation to it (see the example below) ...

var s = Snap("#svg");

var anim1 = function() { 
    triangleClone.animate({'transform' : 'r90,200,200 T400,300'}, 1000, mina.linear, anim2);
}

var anim2 = function() {
    triangleClone2.animate({'transform' : 'r180,200,200 T100,700'},1000, mina.linear, anim3);
}

var anim3 = function() {
    triangleClone3.animate({'transform' : 'r270,200,200 T-300,400'},1000);
}



var triangle = s.path("M200 200,L600,500 L200,500 L200,200");
var triangleClone = triangle.clone();
var triangleClone2 = triangle.clone();
var triangleClone3 = triangle.clone();

anim1();

async.js ...

:

async.series([
    function(callback) {
     whatever.animate({ transform: "s-1,1t0,200" }, 1000, mina.linear, callback);    
    },
    function(callback) {  
     whatever.animate({ transform: "t500,200s-1,1" }, 1000, mina.linear, callback);    
    },
    function(callback) {  
     whatever.animate({ transform: "t500,200s1,1" }, 1000, mina.linear, callback);    
    },
    function(callback) {  
     whatever.animate({ transform: "t0,200s1,1" }, 1000, mina.linear, callback);    
    }
]);
