Hi Support Team,

I am using a Devextreme component in my application. Its a DateTime picker. Something like in this page https://js.devexpress.com/Demos/WidgetsGallery/Demo/DateBox/Overview/jQuery/Light/ But it is not working properly. When I checked with them, they asked me to make sure that the Date.prototype methods are not overwritten in the project. In my project I see the following code in AppPrebootstrap.ts

 private static configureLuxon() {
        let luxonLocale = new LocaleMappingService().map(
            'luxon',
            abp.localization.currentLanguage.name
        );

        DateTime.local().setLocale(luxonLocale);
        DateTime.utc().setLocale(luxonLocale);

        if (abp.clock.provider.supportsMultipleTimezone) {
            Settings.defaultZoneName = abp.timing.timeZoneInfo.iana.timeZoneId;
        }

        Date.prototype.toISOString = function () {
            let value = DateTime.fromJSDate(this).setLocale('en').setZone(abp.timing.timeZoneInfo.iana.timeZoneId).toString();
            return value;
        };

        Date.prototype.toString = function () {
            let value = DateTime.fromJSDate(this).setLocale('en').setZone(abp.timing.timeZoneInfo.iana.timeZoneId).toString();
            return value;
        };

        DateTime.prototype.toString = function () {
            let date = this.setLocale('en').setZone(abp.timing.timeZoneInfo.iana.timeZoneId) as DateTime;
            return date.toISO();
        };
        locale(abp.localization.currentLanguage.name);
    }

Can you please let me know why the prototype classes are overridden in the above function? I tried commenting the following lines but did not see any changes in the application.

Date.prototype.toISOString = function () {
            let value = DateTime.fromJSDate(this).setLocale('en').setZone(abp.timing.timeZoneInfo.iana.timeZoneId).toString();
            return value;
        };

        Date.prototype.toString = function () {
            let value = DateTime.fromJSDate(this).setLocale('en').setZone(abp.timing.timeZoneInfo.iana.timeZoneId).toString();
            return value;
        };

        DateTime.prototype.toString = function () {
            let date = this.setLocale('en').setZone(abp.timing.timeZoneInfo.iana.timeZoneId) as DateTime;
            return date.toISO();
        };
