Velocity mutating options object w/ sequences

[fattenap]

I store animation options in an array. For example var optionsArray = [{stagger: 75, drag: true}]. I then pass optionsArray[0] to Velocity as the options argument.

Velocity("transition.slideUpIn", optionsArray[0]);

This passes in optionsArray[0] as a reference to Velocity. Velocity then adds a delay property to the passed in options object, effectively mutating my options object. Now optionsArray[0] looks like this => {delay:875, stagger:75, drag: true;}

The next time I call Velocity("transition.slideUpIn", optionsArray[0]); it passes in {delay:875, stagger:75, drag: true;} which delays the animation. This compounds for each subsequent call as delay gets longer and longer.

Here's a CodePen showing the issue http://codepen.io/fattenap/pen/IglzH

Would it be possible for Velocity to take a copy of passed in options if it intends on mutating it. This way my object won't be affected.

Thanks

@fattenap yep, that's indeed a problem.

@julianshapiro probably means wrapping all arguments[..] references in animate() with something like $.extend({}, ...).

Agreed. The fix is simple. Expect this in the next update. Thanks, guys.

Done. Please test, confirm it works, and get back to me. Thank you so much!

Tested and it works.

Thanks!
