Using the spread operator
const firstObject = { sampleData: 'Hello world', a: 1, b: 2, c: '3', d: '4', e: {}, f: [] } const secondObject = { moreData: 'foo bar', g: 5, h: '6', j: null, k: undefined } const finalObject = { ...firstObject, ...secondObject };
Using Object.assign
const firstObject = { sampleData: 'Hello world', a: 1, b: 2, c: '3', d: '4', e: {}, f: [] } const secondObject = { moreData: 'foo bar', g: 5, h: '6', j: null, k: undefined } const finalObject = Object.assign({}, firstObject, secondObject);
Loop
const firstObject = { sampleData: 'Hello world', a: 1, b: 2, c: '3', d: '4', e: {}, f: [] } const secondObject = { moreData: 'foo bar', g: 5, h: '6', j: null, k: undefined } const finalObject = {}; [firstObject, secondObject].forEach(object => Object.entries(object).forEach(([k, v]) => finalObject[k] = v))
