Override the moment js default invalid date text

Question

How can I override the moment.js

var defaultInvalidDate = 'Invalid date';

without changing the moment.js file. Just like my site overrides certain bootstrap css styles with a Site.css, so when bootstrap is updated I dont lose the changes, is there any way to make overrides for momentjs?

Thanks in advance

Just update your current locale used by moment.js using moment.updateLocale(localeName, config)

moment.updateLocale(moment.locale(), { invalidDate: "Invalid Date Updated" })

Here is the working example:

console.log(moment(new Date("Aa")).format(""));
moment.updateLocale(moment.locale(), { invalidDate: "Invalid Date Updated" })
console.log(moment(new Date("Aa")).format(""));
