Warning

This lib cannot detect and don't replace below case. Please check whether there is no such a case.

destructive use

Because moment.js is mutable but dayjs is immutable.

ex.

for (const d = moment(); d.add(1, 'date'); d++) {
  console.log(d.toDate());
}

variable assign

ex.

const d = moment();
// error unless you use objectSupport plugin
console.log(d.add({ date: 1 }).toDate());

I recommend to use ObjectSupport plugin

Test

$ yarn jest
