京东风格的轻量级移动端 React 组件库，支持一套代码生成 H5 和小程序

import { bound } from "./bound";
export function rubberband(distance, dimension, constant) {
    return distance * dimension * constant / (dimension + constant * distance);
}
export function rubberbandIfOutOfBounds(position, min, max, dimension) {
    var constant = arguments.length > 4 && arguments[4] !== void 0 ? arguments[4] : 0.15;
    if (constant === 0) return bound(position, min, max);
    if (position < min) return -rubberband(min - position, dimension, constant) + min;
    if (position > max) return +rubberband(position - max, dimension, constant) + max;
    return position;
}
