Some code snippets

获取最大的 Zindex 元素

export const getMaxZIndex = () => {
  return (
    Array.from(document.querySelectorAll("body *"))
      .map((a) => parseFloat(window.getComputedStyle(a).zIndex))
      .filter((a) => !isNaN(a))
      .sort((a, b) => a - b)
      .pop() || 0
  );
};
// getMaxZIndex() + 1

Trim End 指定字符

const trimEndBy = (str: string, dep = " ") =>
  Array.from(str === dep ? "" : str).reduceRight(
    (pre, acc) => (pre === dep ? acc : acc + pre),
    ""
  );

Cache async

/**
 * Cache a asynchronous function
 *
 * @param call original call
 * @returns cached call
 */
export function cacheAsync<T extends unknown, U extends unknown[]>(
  call: (...args: U) => Promise<T>
): (...args: U) => Promise<T> {
  let pendingTask: Promise<T>;
  return function (...args: U) {
    if (!pendingTask) {
      pendingTask = call(...args);
    }
    return pendingTask;
  };
}
