variables declared with let and const in JavaScript are hoisted. However, unlike variables declared with var, they are not initialized with a default value (undefined) during the hoisting process.Instead, let and const variables enter a "temporal dead zone" (TDZ) from the start of the block until the declaration is encountered. Accessing the variable in this TDZ will result in a ReferenceError. This behavior ensures that you cannot access let and const variables before they are declared in the code.Here's an example to illustrate this:console.log(a); // ReferenceError: Cannot access 'a' before initialization
let a = 10;

console.log(b); // ReferenceError: Cannot access 'b' before initialization
const b = 20;In contrast, a variable declared with var would be hoisted and initialized to undefined:console.log(c); // undefined
var c = 30;So, while let and const are hoisted, they behave differently compared to var due to the temporal dead zone and the lack of automatic initialization.

Just wanted to correct you. Let and const also hoisted, but the variables declared will be in temporial dead zone so we can't access it.

console.log(x); //var variable
console.log(y); // Reference error
