Next, you'll create an object to represent the first frame of your animation. Your object should have two properties or keys: inputVal, and addElDelay.

inputVal will represent the value of the input each time your recursive function runs. And addElDelay will be the delay between adding DOM elements to the page.

Add an object to animationData with an inputVal property set to 5, and an addElDelay property set to 1000.

--hints--

The animationData array should have a length of 1.

assert.lengthOf(animationData, 1);

The animationData array should contain an object.

assert.isObject(animationData[0]);

You should add an inputVal property to the object.

assert.property(animationData[0], 'inputVal');

You should set the value of the inputVal property to the number 5.

assert.propertyVal(
  animationData[0],
  'inputVal',
  5
);

You should add an addElDelay property to the object.

assert.property(animationData[0], 'addElDelay');

You should set the value of the addElDelay property to the number 1000.

assert.propertyVal(
  animationData[0],
  'addElDelay',
  1000
);
