You can export the variable from first file using export.

//first.js
const colorCode = {
    black: "#000",
    white: "#fff"
};
export { colorCode };

Then, import the variable in second file using import.

//second.js
import { colorCode } from './first.js'

Using Node.js you can export the variable via module.

//first.js
const colorCode = {
    black: "#000",
    white: "#fff"
};
module.exports = { colorCode };

Then, import the module/variable in second file using require.

//second.js
const { colorCode } = require('./first.js')

You can use the import and export aproach from ES6 using Webpack/Babel, but in Node.js you need to enable a flag, and uses the .mjs extension.
