JavaScript regex

Question

Please help,

What would I have to add to this code below to allow the option for zip codes with 6 digits?

function isUSAZipCode(str)
{
return /^\d{5}(-\d{4})?$/.test(str);
}

Answer 1

return /^\d{5,6}(-\d{4})?$/.test(str); ?

Answer 2

/(^\d{5}$)|(^\d{5}-\d{4}$)/

Answer 3

/^\d{6}(-\d{4})?$/

Simple replace 5 with 6 now it will allow 6 digit
ex :

231301-2123 //pass
618464 //Pass

if u want both
u can use 5 || 6 or 5,6

/^\d{5||6}(-\d{4})?$/
/^\d{5,6}(-\d{4})?$/

It's one of the concept taught in Sololearn itself. You can use {A,B} to specify the repeation range of a sub regex. I would like to memorize it as {N} is derived from the syntax.
