Composing JS Objects

composing-js-objs.js

const a = 'a';
const b = 'b';
const oA = { a }; // ES6 shortcut, same as const oA = { a: a };
const oB = { b };

//composing objects with ES6 spread operator
const c = {...oA, ...oB}; // { a: 'a', b: 'b' }

//composing objects with Object.assign()
const d = Object.assign({}, oA, oB); // { a: 'a', b: 'b' }
