Hello, students! This is Yalko.
Yes24 is promoting me as the developer of the month for March and is holding an event.
Those who purchase IT/mobile books worth 30,000 won or more, including Yalko books, will receive a Goodreader pen pouch on a first-come, first-served basis.
Among those who leave a review of [Yalko's TOO MUCH Friendly HTML+CSS+JavaScript], 10 people will be selected by raffle and receive Starbucks coffee.
