Q1. Consider the JavaScript code: if (true) { let count = 5; } console.log(count); What is the most accurate result in a standard JavaScript environment?
A It prints undefined because let is hoisted exactly like var.
B It raises a ReferenceError because count is block-scoped inside the if block. Correct
C It prints 5 because let variables are always global.
D It prints true because the if condition becomes the value of count.
Explanation
let and const declarations are lexical declarations in ECMAScript. A let variable declared inside a block is bound to that block's lexical environment, so code outside the braces cannot access count.
