[Vuejs]-Typescript Date Issue (VueJS)

For what its worth and those that helped here is what I found comparing the new project with the old.

In the old project, if I follow the definition of Date to where it was defined I was directed to the the file: node_modules/typescript/lib/lib.es5.d.ts and the definition was:

interface DateConstructor {
    new(): Date;
    new(value: number | string): Date;
    new(year: number, month: number, date?: number, hours?: number, minutes?: number, seconds?: number, ms?: number): Date;
    (): string;
    readonly prototype: Date;
    /**
     * Parses a string containing a date, and returns the number of milliseconds between that date and midnight, January 1, 1970.
     * @param s A date string
     */
    parse(s: string): number;
    /**
     * Returns the number of milliseconds between midnight, January 1, 1970 Universal Coordinated Time (UTC) (or GMT) and the specified date.
     * @param year The full year designation is required for cross-century date accuracy. If year is between 0 and 99 is used, then year is assumed to be 1900 + year.
     * @param month The month as a number between 0 and 11 (January to December).
     * @param date The date as a number between 1 and 31.
     * @param hours Must be supplied if minutes is supplied. A number from 0 to 23 (midnight to 11pm) that specifies the hour.
     * @param minutes Must be supplied if seconds is supplied. A number from 0 to 59 that specifies the minutes.
     * @param seconds Must be supplied if milliseconds is supplied. A number from 0 to 59 that specifies the seconds.
     * @param ms A number from 0 to 999 that specifies the milliseconds.
     */
    UTC(year: number, month: number, date?: number, hours?: number, minutes?: number, seconds?: number, ms?: number): number;
    now(): number;
}

declare var Date: Date;

In the above code block declare var Date: Date; appears to be the culprit.

In the new project if I follow the Date defintion I’m sent to: node_modules/typescript/lib/lib.es5.d.ts (exact same file) but the definition for Date is now:

interface DateConstructor {
    new(): Date;
    new(value: number | string): Date;
    new(year: number, month: number, date?: number, hours?: number, minutes?: number, seconds?: number, ms?: number): Date;
    (): string;
    readonly prototype: Date;
    /**
     * Parses a string containing a date, and returns the number of milliseconds between that date and midnight, January 1, 1970.
     * @param s A date string
     */
    parse(s: string): number;
    /**
     * Returns the number of milliseconds between midnight, January 1, 1970 Universal Coordinated Time (UTC) (or GMT) and the specified date.
     * @param year The full year designation is required for cross-century date accuracy. If year is between 0 and 99 is used, then year is assumed to be 1900 + year.
     * @param month The month as a number between 0 and 11 (January to December).
     * @param date The date as a number between 1 and 31.
     * @param hours Must be supplied if minutes is supplied. A number from 0 to 23 (midnight to 11pm) that specifies the hour.
     * @param minutes Must be supplied if seconds is supplied. A number from 0 to 59 that specifies the minutes.
     * @param seconds Must be supplied if milliseconds is supplied. A number from 0 to 59 that specifies the seconds.
     * @param ms A number from 0 to 999 that specifies the milliseconds.
     */
    UTC(year: number, month: number, date?: number, hours?: number, minutes?: number, seconds?: number, ms?: number): number;
    now(): number;
}

declare var Date: DateConstructor;

The DateConstructor interface appears to be the same but the declare var Date: DateConstructor; appears to be the correct implementation.

So, again, no idea what happened with this. I do not play around in the core files so not sure how this file got ‘corrupted?’. Thanks again for everyone who jumped in on this so quickly.
