Library System Using JavaScript with Free Source Code

Introduction

In today’s digital world, managing a library efficiently is essential. A Library System helps in organizing books, tracking borrowed items, and streamlining the entire library process. In this post, we present a Library System built using JavaScript, a lightweight and efficient project perfect for educational purposes. This system allows users to manage their collections, borrow books, and track returns. Best of all, the source code is available for free download, providing a perfect learning opportunity for developers looking to enhance their JavaScript skills.

    if (this.read) {
        console.log(this.read);
        return this.title + " by " + this.author + ", " + this.pages + " pages, Has read.";
    } else {
        console.log(this.read);
        return this.title + " by " + this.author + ", " + this.pages + " pages, Has not read.";
    }
}
