Guide on smoothly transitioning between 2 points within a requestAnimationframe iteration

Would it be possible to acquire a library for this task, or does anyone have any suggestions for my psuedocode API?

Inquiry:

How can I create a function that accepts 4 parameters

interpolate(start, end, time, ease)
and smoothly transition between the start and end numbers over a specified period of time with easing?

Challenge:

I find this particularly difficult because I am uncertain about managing time and easing within a requestAnimationFrame loop. Additionally, I am unsure how to implement the bezier curve handler and optimize the code if necessary.

  interpolate(start:number, end:number, time:number, ease) {
    // code for easing
    return value;
  }

  function _draw() {
    currentValue = interpolate(0, 10, 0.7, 'cubic-bezier(.62,.28,.23,.99)');
    if(currentValue !== lastValue) {
      console.log(currentValue)
    }
    requestAnimationFrame(_draw);
  }

Eventually, the final tick of the transition process should log out a value of 10 as the currentValue.

If you're looking for generic easings, I recommend using the Penner Equations. You can find these functions on GitHub as a library called Penner Equations. Another useful library to consider is tween-functions.

Here's a simple demo showcasing how the value is calculated on each frame:

const Easings = [
  function easeInQuad(t, b, c, d) {
    return c * (t /= d) * t + b;
  },
  // other easing functions omitted for brevity
];

const duration = 2000;
const div = document.querySelector('div');

let start = Date.now();
let from = 0;
let to = 300;
let fnCounter = 0;
let fn = Easings[fnCounter];
// tick function and CSS styling code removed

requestAnimationFrame(tick);

If you need custom bezier curves, I suggest using the bezier-easing library. The calculations remain the same: on each tick, you calculate the elapsed time and determine the percentage from the duration. This gives you a tick value ranging from 0 to 1 on every frame.
