#TIL

• To use functions that are in a non-main.js script file, you must use export and import keywords. In the non-main.js file, you must designate the function you want to export by putting export keyword in front of the function.
• To successfully import the function to the main.js file, you need to explicitly state import { nameOfFunction } from 'path'.
• Reminder that you must use both export and import - they go in pairs.

Example:

non-main.js file

export function addTwo(number) {
    const sum = number  + 2;
    return sum; 
}

main.js file

import { addTwo } from './non-main.js'

addTwo(5);
