Javascript Interview Questions

[AnujyotiDe-vflx]

It shows error as let is block scope and in the intialization x is used twice.

[SonuGangde]

With let it will throw reference error : x is not defined

[memaster]

we cannot access the let x before initialization error

[ProgrammingBoy]

Y ka liye not defined ayaga kuki x hoisting ka bajai se undefined set ho jayaga but y nahi milega to y kae liye must error ayaga

[Efootballgame]

Identifiter ‘x’ has already been declared

[agamprakashmishra]

ReferenceError.
b/c <let> doesn't supports hoisting and
<x> in the array will be accessed before it's declaration.
Am I right sir..¿?

[Shadoowwss]
