 *
 * @param {number} current - The starting value.
 * @param {number} target - The end value.
 * @param {number} factor - The interpolation factor, typically between 0 and 1. A lower value results in slower interpolation, while a higher value makes it faster.
 * @param {number} delta - Time elapsed since the last update in milliseconds
 * @param {number} [approximation=0] - A small threshold to determine when the difference between the interpolated value and the target is negligible. If the difference is within this threshold, the function returns `target` directly.
