小程序支持javascript里的replace吗Cannot read pro

• Cannot read property 'replace' of undefined;at App getGoodsWeek function

getGoodsWeek:function(){

let date = ‘2018-12-13 16:00’;

   let getGoodsDate = new Date(date.replace(/-/g, “/”));

};

为什么会报错,小程序不支持javascript里的replace吗？

Cannot read property ‘replace’ of undefined;at App getGoodsWeek function
