destructuring.js

const someObject = {
    a: "Some Value"
//     ^ Input
//  ^ Output: someObject.a
}

const { a: a } = someObject
//         ^ Output: `const a`
//      ^ Input: someObject.a

// When the key and value are the same you can just use one:
const b = 'B'
const nextObject = { b }
//                   ^ Input/Output: `nextObject = { b: b }`
console.assert(nextObject.b === b) // true


// LOOK! I can create a new scope to avoid declaring the same variable twice!
{
    const { b } = someObject
//          ^ Input/Output: `const b = someObject.b`
    console.assert(b === nextObject.b)
}
