"if you still use var for some reason"
Yo I felt that 😭😂

My version of the “use const instead of var” rule is “use ts instead of js”

[virajjoshi]

I'm little confuse, If I use function and declare variable using var, then why it's not accessible outside function.

You can also declare them without the "const, let or var" keyword, then they will become global variables instead :)

What about just `something = 4`? Seems like languages are overcomplicating things.

What extension are you using that puts the lint messages typed out instead of the red line under the error

[boluaygepong]

[prestonmatson]

is there ever really an instance when you need to declare a variable that shouldn’t be block scoped?

[farhanaditya]

What if I don't say anything? I mean like just "name = `wdj`"

[LordMarcus]

I love JavaScript, but it is a fucking semantic mess.

[peterkrau]

Is this quokka? How do you get this nice inline errors?
