[pravinmhalsekar]

Var has functional scope, let has block scope, so b variable will not be able to access the value from if loop block

[solankiviral]

Because let is blocked scope and var is universal scope ❤

[MrDoug]

let has a limited scope - it reaches only “if block” scope.

[abhishektalwar]

Let has block scope never output outside the if statement Vs Var has global scope it output outside the if statement

[ramighazzawi]

Var is Function scope and let is block scope

[davejackson]

cuz b is in a block scope and that's the why of meaning among global and local var

[KarthikKarthik-qlkb]

b inside block scope, it's not accessible globally

[TheMisterSpok]

B/c of block scoped 'let' declaration. Duh
