Tests:
  • Using the spread operator

    AخA
     
    let firstObject = { sampleData: 'Hello world' }
    const secondObject = { moreData: 'foo bar', a: 1, b: 2, c: false, d: 'hello' }
    firstObject = {
        ...firstObject,
        ...secondObject
    };
  • Using Object.assign

     
    const firstObject = { sampleData: 'Hello world' }
    const secondObject = { moreData: 'foo bar', a: 1, b: 2, c: false, d: 'hello' }
    Object.assign(firstObject, secondObject);
