Convert getFullYear to 2-digit format

[O.B.]

I'm trying to convert the current year into a 2-digit format. Since
getYear returns 106, I'm trying to perform a substring of getFullYear()
with no luck. What am doing wrong?

currentTime = new Date()

var result = "FY" + currentTime.getFullYear().substring(2, 4)

var result = "FY" + (currentTime.getFullYear())%100;

Or, just use getYear and do the same thing with %100

getFullYear returns a number, not a string. To use the String object's
substring method, convert the result to a string by concatenating an
empty string to the result of getFullYear:

stringYear = currentTime.getFullYear() + '';

currentTime = new Date()

var result = "FY" + currentTime.getFullYear().substring(2, 4)

If only ever dealing with 4 digit years, then:

var result = FY + (currentTime.getFullYear() + '').substring(2,4);
You could also use the replace method:

var result = ('FY' + currentTime.getFullYear()).replace(/\d\d/,'');
But using modulus operator is probably neater...
var result = "FY" + (currentTime.getFullYear())%100;

Or, just use getYear and do the same thing with %100

For years yy00 to yy09 that will return a single digit, the OP may want
to add a leading zero:

result = (result < 10)? '0' + result : '' + result;

getYear does not necessarily return 106; it can return 2006 or 6,
depending on browser.

On the Internet, getYear should only be used if either the year will
be in 1900..1999 or it is effectively followed by code restricting the
value to 0..99 or "00".."99".

Don't rely on luck; read the newsgroup FAQ, carefully.

currentTime = new Date()

var result = "FY" + currentTime.getFullYear().substring(2, 4)

var result = "FY" + (currentTime.getFullYear())%100;

Or, just use getYear and do the same thing with %100

The OP, in Subject and Body, calls for a 2-digit format. Your code, for
10% of years including around now, gives 1-digit.

R = "FY" + String(currentTime.getFullYear()).substring(2, 4)

R = ("FY" + currentTime.getFullYear()).replace(/(..)..(..)/, "$1$2")

R = "FY" + LZ(currentTime.getYear()%100)
