16: JavaScript Scopes | Local Scope and Global Scope in JavaScript | JavaScript Tutorial | mmtuts

The resource heavy stuff is the only thing i dont know. and was new to me, thanks! it was so informative and useful for my visit in your channel

Thank you so much for the fast and easy explanation :) saved me a lot of time :)

Hmm love your plants man! What plants are there ? And also the pots, super nice!

Thanks for the vid but waay too much treble in your vocal mix.

I was just thinking, "oh, in that case I'll create variables outside of the functions!" then I got roasted with some facts about the downsides lol

within 2 minute you explained it better than the almighty "yOu DoNT kNOW Js" book... getting a little annoyed at the overcomplicated examples in that book.

thank you! this the only video that showed clear examples and your explanation was clear. Please keep creating content

not seeing why the <form> tag was necessary. Great tutorial tho!

bruh thank you this was a breeze amazing teaching abilitys my boy

Nice videos

Thank you so much, right now I know what variable scope is and I'm waiting for the next lesson
and thank you again🙏🙏🙏

Thanks man, 10 times better than Udemy explanation. “You're an amazing teacher !!!

Thank you. Wasn’t getting what I needed out of my course so stopped in here in order to get some quick info. You cleared up what I needed to know in a matter of minutes. Thumbs up, thank you again!

5 JavaScript Scopes explained.
1. Global Scope
All other scopes are defined inside of this scope so variable defined here will be available in all other scopes.
2. Local Scope
This can be any scope, for example two variable defined in a Function scope are local to each other.
3. Function Scope
You create a function and it creates a scope, it's that simple, any variable defined here will not be available outside the scope. not even variable defined with var keyword.
4. Block Scope
This scope is created simple by wrapping variable inside {} braces, variable will not be available outside the scope
5. Lexical Scope
Lexical scope means the children scope have the access to the variables defined in the parent scope.

I love the way you explain. Thanks for your videos

Your vidoes are the best man! Thank you very much. Almost gave up learning JS

how to share variables between two functions ?

this is outdated topic, as new keyword "let" and "const" added new scope called block scope

thanks !

Thank you so much! I was really confused on this one but this video helped explain it alot. I'm very grateful!

Instead of console.log you could use return its more professional

You look like Elon Musk!!!

Thank you!

After watching the video: local scope makes the site heavier only when we call the function. global scope makes the site heavier on load. local scope also cant be used outside of the function? and global scope yeah

Thank you so much that helped me a lot to understand the different between Global Scope and Local Scope.

me n my bro lernt JavaScript from u sir gr8 effert

You explain things much more clearly than the guys whose course i paid for lol. straight to the point you go and its effective! Thank You!!

You're intro on the past like 5 videos is the EXACT same and its hilarious its like it was all dubbed over hahahahah

where is the fox on the shelf from?

10.

thank you a lot I really appreciate the time you dedicate you are putting in the videos

Thanks!!! I recently started learning to code and this helped a lot!

Super clear and helpful. Thank you! Cleared up some confusion on my part.

The best JS course on YT!

Hi @mmuts, I have a question about this topic. I created a variable inside if statement (block scope) and tried to access it inside a function (function scope) and it was successful. Are variables declared inside a block scope considered also as declared globally? Or it's just because of hoisting? Thanks more power! Love your tutorials! :)

THe Alchemist do you suggest for reading

Am I the only one who noticed KURAMA??

Thank you brotha for putting this video out!. I have been working with functions for a good couple months and hearing this, in the beginning, was super confusing me as I'm a hands-on visual learner but after building a few things on my landing page and seeing functions being used to what I'm looking for hearing global and logical scope makes a lot more sense!. Keep up the great work your content is great. :D

being able to see the instructor is helpful for some odd reason. also, the hand gestures help with the explanation lol great videos

Thank you so much, I finally understood the global and local scope!

Best Teacher Ever

amazing videos i have a question if i finished that 35 videos of JS i will know every thing about JS or not????

you seem really happy about confusing us

These videos are just great, thanks man for not being a bad teacher :)

I like how you pronounce "var" as in the Danish "was", and not like a cutout from the word "variable". I live in Denmark and I find this quite funny (in a good way) :D

What's the difference between console.log and return statement?
