Image: JavaScript getYear Method Problem
Description: Webpage screenshots showing the JavaScript .getYear method problem. It depicts the so-called Year 2000 problem. The results of the .getYear method are different with Internet Explorer 6-8 and the other modern browsers: IE3, IE9+, other modern browsers: .getYear always returns a 2-digit value that is the stored year minus 1900). IE4-8, other modern browsers: .getYear returns a 2-digit value that is the stored year minus 1900) for the years 1900 through 1999; it returns the 4-digit full year for dates outside that range. .getYear is now obsoleted, but supported for backward compatibility by all modern browsers. .getFullYear is not supported before IE6. With those that support it, the 4-digit full year is always returned. This method is currently recommended.
