JavaScript - IsDate

Good snippet to see if string is a valid date. Returns bool.

 


const IsValidDate = (string) =>
{
    if (string === null)
    {
        return false
    }

    // If the date is valid then the getTime() method will always be equal to itself.
    // If the date is Invalid then the getTime() method will return NaN which is not equal to itself.
    let d = new Date(string);
    let results = d.getTime() === d.getTime();
    return results;
};
