With this code you link layername to layername2 in the same comp
app.project.item(1).layer("layername").parent = app.project.item(1).layer("layername2");

not work for one comp to other comp’s layer to link 😉
app.project.item(1).layer("first_comp_a_layer").parent = app.project.item(2).layer("second_comp_a_layer");

return (t==0) ? b : c * Math.pow(2, 10 * (t/d - 1)) + b;
this code is a different if expression. means;
if(t==0){
return b;
}else{
return c*something+b;
}
such as
value = (a==1) ? "hello":"bye";
same
if(a==1){ value = "hello"; } else {value = "bye";}

These codes make a value easein, easeout and easeinandout

in this example you can see the

var compone = curComp.layer(1);
var comptwo = curComp.layer(2);
comptwo.startTime = compone.outPoint;

layer’s has startTime and outPoint. outPoint is endtime of layer.
You make your first item(myComp)’s start time as timeToSet on your code.

You should use startTime = 10; instead of startTime.setValue() function.
