Do not deduplicate . The intention of duplicate keys is to allow for a jump from one end value to a start value. The simplest implementation is to replace duplicates with a minimally larger number, eg.

0, 0.5, 0.5,1
0, 0.5, 0.5000001, 1

Check if there is a THREE.epsilon .

This avoids additional checking in the easing function which is called a lot.

• update design
• properties

expose tween interpolation methods

Check what a-animation does

• use custom easing or custom interpolation

[0,1] is only useful for a single to value. Change default to [0, 1/n, 2/n, n/n]
n = to.length -1

check if component pause and play make sense:
A-animation takes care of pause and play, should work.

Test

investigate. Tween seens NaN as from if not given.

Check if all .properties need from, eg. material.color

may have to do with Tween array.

tests for regular use with single to value and no keys
: basic example
tests for incorrect number of keys: too many should be ignored, too few filled in.
tests for weird values in to
tests for duplicate keys: basic example
and decreasing keys
