Setting variables in if statement using JavaScript throw error (already declared)

Question

I have this code

if (found === true && premium === 'active' || premium === 'trialing') {
  var free = false
} else {
  var free = true
}

The express server works fine on both localhost and remotely on Heroku, I tried deploying this app to firebase hosting, one the error that prevented me to deploy is

75:17 error 'free' is already defined no-redeclare

I am not sure how to fix that, my goal is simply to pass free variable with a response like so

response.render('master.html', { links, profile, free })

have you tried putting var free before the if, and inside (if and else) just the assignation without var keyword? — Eduardo Pascual Aseff

You can declare this way and remove the else condition

let free = true;
if (found === true && premium === 'active' || premium === 'trialing') {
   free = false 
}

https://eslint.org/docs/rules/no-redeclare

var free = true;
if (found === true && premium === 'active' || premium === 'trialing') {
  free = false
}

Thanks! the idea is there but I believe to either use global let or set variable like free = true
