switch nonsense

switch.js

const someVar = 'foo'

// the bad way
switch(someVar) {
  case foo:
    const response = 'someVar is foo!'
    break
    
  case bar:
     const response = 'someVar is bar!' // errors, 'assigning to constant variable response'
     break
     
  default:
    const response = 'idfk'
}

// the good-ish way? i guess?
switch(someVar) {
  case foo: {
    const response = 'someVar is foo!'
  }
    
  case bar: {
     const response = 'someVar is bar!'
  }
     
  default: {
    const response = 'idfk'
  }
}
