Sammie Bae is a data engineer at Yelp and has worked for the data platform engineering team at NVIDIA. He developed a deep interest in JavaScript during an internship at SMART Technologies (acquired by Foxconn), where he developed Node.js-based JavaScript APIs for serial port communication between electronic board drivers and a web application. Despite how relevant JavaScript is to the modern software engineering industry, there were no books that taught algorithms and data structures using JavaScript. Sammie understands how difficult these computer science concepts are and aims to make clear and concise explanations.
