Javascripting Exercise 2 - Variables

[caro-turnbull]

I'm stuck on the second exercise. Instructions are:
Create a file named variables.js.
In that file declare a variable named example.
Make the variable example equal to the value 'some string'.
Then use console.log() to print the example variable to the console.
Check to see if your program is correct by running this command:
javascripting verify variables.js

So,
I've created a file called variables.js. I open that file with:
nano variables.js

Then I type this in the file: (this where I think I've missed something or messed up??????)
let example
const example = 'some string'
console.log(example)

Save and exit. Then I verify and I get this error...

Error: Command failed: node "/Users/carolineturnbull/lighthouse/javascripting/variables.js"

@caro-turnbull bro
in your code
let example const example = 'some string' console.log(example)
it should be
const example = 'some string' console.log(example)
filrst you have declare example variable with let in 1st line then in 2nd line you declaring it with const
use let or const for same variable name
