You won't need to use prompt in this challenge. Just encode your names as literal strings.

You also won't modify the initial values after assignment. In a later step, you will create a new variable to combine them.

Also, let and const begin with lower case letters. No need to mix them. They can both be let.

Assign your name to the variables just means to add your name to each variable as 'strings'.

Also, if you intend to eventually change or update the values of your variables, choose 'let'. Otherwise, keep 'const'.

As you might have learned earlier in the course, 'var' is no longer used due to scoping reasons. Meaning, it can be seen inside or outside code blocks and could potentially harm your code by changing values of your 'var' unintentionally.

Let example:
let x = 1;
let z = 2;
x + z = 3;
x = 2;
x+ z = 5;

Const example: const x = 2; const z = 5; x = 10; // this will return as undefined x + z = 7;

Assign a number to variable x,

x =
