Published by Factor in
regexvalidation

Create a RegExp myRegExp to test if a string is a valid pin or not.

A valid pin has:

  • Exactly 4 or 6 characters.
  • Only numerical characters (0-9).
  • No whitespace.

Examples

myRegExp.test("1234") ➞ true

myRegExp.test("45135") ➞ false

myRegExp.test("89abc1") ➞ false

myRegExp.test("900876") ➞ true

myRegExp.test(" 4983") ➞ false

Notes

  • Empty strings should return false when tested.
