一套前端设计语言和基于React的实现

export const CURRENT = new Date();
export const CURRENT_DAY = new Date(CURRENT.getFullYear(), CURRENT.getMonth(), CURRENT.getDate());
export const CURRENT_YEAR = CURRENT.getFullYear();
export const CURRENT_MONTH = CURRENT.getMonth();
export const CURRENT_DATE = CURRENT.getDate();
export const ONEDAY = 24 * 60 * 60 * 1000;

export const padLeft = (val) => {
  return val < 10 ? `0${val}` : val;
};

export const getMonthStr = (val) => {
  return `${val.getFullYear()}-${padLeft(val.getMonth() + 1)}`;
};

export const getDateStr = (val) => {
  return `${val.getFullYear()}-${padLeft(val.getMonth() + 1)}-${val.getDate()}`;
};

export const isSameDate = (val, cmp) => {
  return val.getFullYear() === cmp.getFullYear() && val.getMonth() === cmp.getMonth() && val.getDate() === cmp.getDate();
};

export const isCurrentMonth = (val) => {
  return val.getMonth() === CURRENT_MONTH;
};

export const isBeforeMonth = (val, cpr) => {
  if (val.getFullYear() < cpr.getFullYear()) {
    return true;
  }

  if (val.getFullYear() > cpr.getFullYear()) {
    return true;
  }
  return val.getFullYear() === cpr.getFullYear() && val.getMonth() > cpr.getMonth();
};

export const goDays = (val, diff) => {
  return new Date(val.getTime() + diff * ONEDAY);
};

export const goMonths = (val, diff) => {
  const cp = new Date(val);
  return new Date(cp.setMonth(cp.getMonth() + diff));
};

export const goYears = (val, diff) => {

};

export const isArray = (val) => {

};

export const isFunction = (val) => {
  return Object.prototype.toString.call(val) === '[object Function]';
};
