How do I change the value of an imported variable?

import Foo from 'file'

if (inDevelopment) {
  Foo = null
}

I would like to do this, but it results in

SyntaxError: "Foo" is read-only

Is there anything that changes the default const behavior, like let import Foo from 'file'? 😊

You don't. Use a second variable:

import Foo from 'file'

const LocalFoo = inDevelopment ? null : Foo;

Only the module that exported the variable can change its value, although non-constant exports are weird to work with.
