ES2015 destructuring

ES2015_destructuring.js

function destructuring( {weight, age, space = null }) {
    // Instead of using something like opts.weight, now just use the property name in the function signature
    console.log(weight);
    console.log(age);

    // Checking for null, standard ES5, as ?? isn't present in ES2015
    console.log(space ? space : 'Space not set');
}

// Block scoped variable using let/const
const age = 30;

// Age is basically set as age: age behind the scenes
destructuring({ weight: 82, age });

// Notice how the params are passed differently than how they're set in the signature?
const weight = 100;
destructuring({ age: 21, space: 'Some space', weight });
