I want to use an exported constant from a JS module. My simple script is like

#!/usr/bin/env node

const pi = require('./custom_math').pi
console.log(pi)

But the module I require has an import, so It raises the following error:

$ ./script.js
<path_to_module>/index.js:1
import anotherconstant from '<other_module>'
^^^^^^

SyntaxError: Cannot use import statement outside a module

How can I make a script that uses the pi constant from the simple_math/index.js file?
