+# Appendix B - api
+
+This is a complete list of accessible functions and parameters that are built into Prosperon. For the most part, developers will concern themselves with the modules, all of which can be imported with `use`.
+
+Types document particular javascript objects with a specific object in their prototype chain, which can allow access to an underlying C data structure. A lot of these are used only internally by Prosperon, but brave developers can pick around in the module internals to see how they're used and do their own thing if they want!

+# tween
+
+### Tween <sub>object</sub>
+
+
+An object providing methods to create and control tweens with additional features
+like looping, custom easing, multiple stages, etc.
+
+Properties:
+- default: A template object with loop/time/ease/whole/cb properties.
+Methods:
+- start(obj, target, tvals, options): Create a tween over multiple target values.
+- make: Alias of start.
+
+
+### Ease <sub>object</sub>
+
+
+This object provides multiple easing functions that remap a 0..1 input to produce
+a smoothed or non-linear output. They can be used standalone or inside tweens.
+
+Available functions:
+- linear(t)
+- in(t), out(t), inout(t)
+- quad.in, quad.out, quad.inout
+- cubic.in, cubic.out, cubic.inout
+- quart.in, quart.out, quart.inout
+- quint.in, quint.out, quint.inout
+- expo.in, expo.out, expo.inout
+- bounce.in, bounce.out, bounce.inout
+- sine.in, sine.out, sine.inout
+- elastic.in, elastic.out, elastic.inout
+
+All easing functions expect t in [0..1] and return a remapped value in [0..1].
+
+
+### tween(from, to, time, fn, cb) <sub>function</sub>
+
+
+
+Creates a simple tween that linearly interpolates from "from" to "to" over "time"
+and calls "fn" with each interpolated value. Once finished, "fn" is called with "to",
+then "cb" is invoked if provided, and the tween is cleaned up.
+
+
+**from**: The starting object or value to interpolate from.
+
+**to**: The ending object or value to interpolate to.
+
+**time**: The total duration of the tween in milliseconds or some time unit.
+
+**fn**: A callback function that receives the interpolated value at each update.
+
+**cb**: (Optional) A callback invoked once the tween completes.
+
+
+**Returns**: A function that, when called, cleans up and stops the tween.
