  • Basic javascript knowledge - this course teaches data structures from the ground up
Description

This course teaches data structures (linked lists, binary search trees, hash tables) from the ground up.  Data structures allow you to improve the efficiency, performance, speed, and scalability of your code/programs/applications.  You will learn what data structures are, why they are important, and how to code them out in JavaScript.  You will also learn other important programming concepts along the way such as recursion, time complexity, the "this" keyword, the prototype object, and constructor functions, since data structures use these concepts by their very nature.  This course heavily uses diagrams and animations to help make understanding the material easier.

This course is also very good for anyone who is interviewing for developer/engineering jobs at both large and small companies.  Interviewers will very often ask candidates to write data structures out in code, and this course will prepare you very well to do that.  If you have recently graduated from a coding bootcamp or are currently looking for a job, you will find this course to be beneficial.  Knowing data structures will help you to excel in technical interviews.

Who is the target audience?
  • Anyone who wants to learn how to code out data structures in JavaScript (introductory)
  • Anyone who wants to learn how to implement data structures in their applications
  • Anyone who is currently, or will be interviewing for engineering/developer roles and wants to be well prepared for technical interview questions
  • Anyone who already knows data structures but needs a refresher
  • Anyone who wants to strengthen their computer science fundamentals

Software Engineer and Instructor

HI! I'm Eric.  I currently work as a software engineer in New York City and I have extensive experience working as a teacher, instructing people in a variety of different subjects.  I changed my career from teaching to software engineering because of the excitement it brings me and the passion that I have for it.  I am lucky enough now to have the opportunity to combine both of these passions - software engineering and teaching!
