16.1: let vs var - Topics of JavaScript/ES6

In this video, I cover the "let" keyword in ES6 JavaScript. I discuss the differences between "let" and "var" (block scope vs. functional scope).

"A variable should have the smallest scope that is needed." I like that.

Love your stuff, Dan! You're becoming my go-to resource, whenever I'm confused about a concept. Keep up the good work!

When I'm down I watch Coding train videos and the sun shines again :) Thanks for being such an awesome human being and teacher!

By playing around with var and let I kind of got the idea of how it worked but once you explained that "hoisting" term, things really got clear and I remembered what my high school programming teacher used to say regarding C++ and Pascal: "If you're going to declare something, do it at the top of the file!".
That really clicked in my brain once you explained what hoisting was :D
Keep up the good work bro. You're killing it!

Awesome video -- your breakdown of the differences between var and let was perfect. I love the energy too. Thanks!

[jermainebrayne]

this was perfectly explained, love the energy!

This doesn't have to be re-done as you said in the video, this is nice honestly, there are so many boring programming videos on the web that the enthusiasm really helps, similar feelings to CodeCourse :)

Keep it up man, 10/10

Awesome video - very clearly defined the diff between var and let !!

[JanneWolterbeek]

This is actually very informative AND entertaining/funny. That is unique, not many have this talent. Makes learning much easier for people like me! Thanks!

[nicksmeta]

Wow, amazing! Your explanation style is so verbose (in a good sense) that I can just listen to many of the videos, while doing chores and stuff, and understand the ideas being presented. Simply marvelous!

[VantazeVibesWorld]

man you are funny and also explaining in good detail at same time. i love this kind of presentation.
thank you.

best video out there explaining let vs. var!

[mattgraves]

Exactly the same issue I have with scope, I learned how to program with Java and think in the same fashion. You are a great teacher! Thank you

Great video, i just started coding, in JS coming from a background in C++, and and i mostly learned to code JS from mini bootcamp that used ES6 and now i am going back and doing intro courses, and a lot of them use var and stuff and write in in concatenated strings over just using a template string, i much prefer the ES6 stuff and i am glad i learned it first.

This guy made me love programming through his lessons
thanks man !

[sowmyavijayakumar]

Wow..this is excellent stuff..i have been wracking my head over let vs var for a while and I finally get it!

[jojojawjaw]

Crystal clear explanation of the difference, thanks a lot! ♥
I've been using var all my life (more like for the few months ago), thinking that the variable is limited to its block like C++ and Java, after watching this, I was like what!

I am learning JS on free code camp now and you explain things so well its surprising easy for me to fill out challenges. thanks a lot and please keep making more videos! its a shame that i havent found your channel earlier
