How to prevent “Invalid date” with Moment.js and JavaScript?

To prevent “Invalid date” with Moment.js and JavaScript, we can check if a date is valid with the isValid method.

For instance, we write:

console.log(moment('2022-01-01').isValid())
console.log(moment('abc').isValid())

to create moment objects with a valid and invalid date string.

Then we can call inValid on each to check if they’re valid dates.

Therefore, the first log should log true since it’s a valid and the 2nd one should log false since it’s not.
