CONSOLE - Declare a Read-Only Variable with the const Keyword

[sofiatroche]

Tell us what’s happening:
Hi!
Why the console log prints
freeCodeCamp is awesome!
and not
freeCodeCamp is cool!

Your code so far

// Only change code below this line
const FCC = "freeCodeCamp";
let fact = "is cool!";
// Only change code above this line

fact = "is awesome!";
console.log(FCC, fact);

@sofiatroche

fact = "is awesome!";

This line changes the value stored in fact. The console.log uses the most recent value that the variable was set to before it is called.

The variable FCC is declared as read-only but the ‘fact’ variable wasn’t. That’s why you can change it

[sofiatroche]

ok, but… fact its defined with let
sigo confundida

[JeremyLT]

You can change a variable declared with let. You can’t change a variable declared with const.

@JeremyLT

You can change a variable declared with let

ok!
so, you can do this
let fact = “is cool!”;
fact = “is awesome!”;

But not this
let fact = “is cool!”;
let fact = “is awesome!”;

[JeremyLT]

Yep. Redeclaration is not allowed with let or const.
