What about performance? Is there a benefit to using const instead of let?

Wait, can you modify an array/object declared with "const"?
I thought const declarations were immutable
Great video btw!

I personally like Rust's take on declaring variables though
In Rust, all variable declarations are immutable by default
Or you need the additional "mut" keyboard to _specifically_ make it immutable
It makes you think whether you will really need to mutate the value

what's the difference with var and let though? why is let better than var?

blackslashXD

'const' is harder to press in keypads than 'let', hahaha, extra two keypress, i hope in the future the jsGroup will change it to 'con' only, haha!

Why not just use "let" all the time? The difference is that let can be reassigned, but what consequense does it have to use let and NOT assign it anything, versus having used const to do so? Seems like "Let" is just flexible when you need it to
