What is scope and hoisting in ES6?

Can you explain what scope means in ES6?

In ES6, scope refers to the accessibility of variables, functions, and objects in some particular part of your code during runtime.

What about hoisting? How does it work in ES6?

Hoisting is a JavaScript mechanism where variables and function declarations are moved to the top of their containing scope during compilation.

Are there any differences in hoisting between var, let, and const?

Yes, variables declared with var are hoisted and initialized to undefined, while let and const are hoisted but not initialized, leading to a ReferenceError if accessed before declaration.

Can you give me an example of hoisting with let and const?

Sure! If you try to access a let or const variable before its declaration, you'll get a ReferenceError. For example:

console.log(x); // ReferenceError
let x = 5;
