Binary Search algorithm in JavaScript

In this video we'll learn what a binary search is, how to use it and code your own.

It just took me 7mins. to understand binary search algorithm. We don't need university professors but we need these type of brilliant coders. Thank you sir❤️

[Sam-czck]

you explained it so well! thank you ;D

[arcosd]

Dude, I only get 6 and mine is identical to yours. Hahaha!

[SimPwear]

Loved this video it helped me understand Binary Search Algo! Did you stop? I thought this was going to be a series😭😭

[sagarsabat]

Hey Leigh,
The binary search was literally becoming a nightmare for me. But, you explained it so beautifully and in simple words. Thank you, sir.

This is the very first Binary Search videos I every watch. Not intimidating at all. Thanks for the simple walk though!

That's weird, i got 6 not 7.... I got 0, 1, 2, 3, 4, 5, 6, 6 I got double six? :)

Javascript beginner here. Why Do we add lower to upper-lower/2 ? Thanks in advance

[matekimagick]

I'm sure this will be obvious once someone points it out, but how is the number 7 at index 7? If 0 is the first index why isn't the index of 7, 8? Great video!!

Hello, does the comparison works if we search through an array of strings values ?

[julielai]

Thank you so much Leigh, hoping to learn more algorithm from you!

[rofazayn]

Whoa man this is so ingenious and genius at the same time, guess it is time for me to start learning algorithms and data structures, thanks so much for the video, all of your content is top notch!

[salmausama]

thank you for this, you explained it so well.

How you find more than one data .... i think and idea

[craftmoon-vas]

Hey man! Love your videos. They are really helping me recently, as a junior dev.
Would love to see more of your google maps videos. I am trying to get familiar with the API, but the documentation is still kinda confusing to me.Specifically regarding using react-google-maps searchbox inside google maps.
Keep up the great work!

Very clean explication, but the middle point can be like:
let middPoint = Math.floor((start + end) / 2);

[yukanagaikoko]

Is lower set to 0 because it's the first element in the array of your example (ie. you can set the variable lower to array[0] instead of hard coding it?) or because it's always the starting lowest value?

find() method, better performance than binary search ..

[samandarmasatov]

Hello, Thank you very much for your lesson.

[quickindiarecipe]

Shouldn't we check if the value is lower or upper first?
