Thank you to the sort videos at Timo Bingmann channel:

Selection sort, an alternative to Bubble sort, is the topic of today's video. If you haven't seen the Bubble sort video yet, make sure to check it out first!

This is a part of my Algorithms and Data Structures playlist series. We cover a lot of common interview questions asked during whiteboards for entry-level developers. Learning to master these takes time, practice, and pattern recognition. So I'll be helping you equip a toolbelt and filling it with as many tools as I can to help prepare you to crush those interviews! Remember: "Luck is where practice meets opportunity."

In this video, we switch gears to Selection Sort. We start with an introduction to the algorithm and its mechanics, followed by a step-by-step walk-through of an example.

Then, it's time for some code. We'll implement the Selection Sort algorithm in JavaScript, explaining each line as we go. You'll leave with a solid understanding and the confidence to code it out yourself.

We'll also delve into the complexity analysis of Selection Sort, breaking down its time and space complexity, and explaining the Big O notation for both. We'll compare Selection Sort to other sorting algorithms, including Bubble Sort, discussing the pros and cons of each and where they each fit into the grand scheme of sorting.

Finally, while Selection Sort might not be the go-to for larger data sets, we'll discuss why learning it is still crucial. Understanding the mechanics of various sorting algorithms, even the simpler ones, provides a solid foundation for more advanced study.

Shouldn't we add "j < len - i - 1" to our inner for loop condition? So we can avoid unnecessary iterations over items that don't exist? Anyways, great lesson as always! Cheers!
