Imports and Modules

• Imports let you break your code into files that reference each other
• Also let you import parts of a library (but not the whole thing!)
• Using imports also opts you into using modules
• Modules make sure that variables and functions from one file don't "leak"
• Let you write bigger projects without worrying about "collisions"

// file a.js
import { addNumbers } from "./b"

console.log(addNumbers(1,2));

// -------------------------------
//file b
export function addNumbers(a,b) {
    return a + b
}
