combine two objects in vuejs

To combine two objects in JavaScript, you can use various approaches. Here are a few common methods:

1. Object.assign(): The Object.assign() method combines multiple source objects into a target object by copying the properties from the source objects to the target object.

const obj1 = { a: 1, b: 2 };
const obj2 = { c: 3, d: 4 };

const combinedObj = Object.assign({}, obj1, obj2);
console.log(combinedObj);
// Output: { a: 1, b: 2, c: 3, d: 4 }

1. In the above example, Object.assign() creates a new object by copying the properties of obj1 and obj2 into an empty object {}.

2. Spread Operator: The spread operator (...) can be used to merge two or more objects into a new object.

const obj1 = { a: 1, b: 2 };
const obj2 = { c: 3, d: 4 };

const combinedObj = { ...obj1, ...obj2 };
console.log(combinedObj);
// Output: { a: 1, b: 2, c: 3, d: 4 }

1. Here, the spread operator is used to spread the properties of obj1 and obj2 into a new object.

2. ES2018 Object Rest/Spread Properties: The Object Rest/Spread Properties syntax allows you to extract specific properties from an object while combining them with other properties.

const obj1 = { a: 1, b: 2 };
const obj2 = { c: 3, d: 4 };

const combinedObj = { ...obj1, ...obj2 };
console.log(combinedObj);
// Output: { a: 1, b: 2, c: 3, d: 4 }

1. The above example is similar to the spread operator approach.

2. Lodash merge(): If you are using the Lodash library, you can utilize the merge() function to combine objects deeply.

const _ = require('lodash');

const obj1 = { a: 1, b: { c: 2 } };
const obj2 = { b: { d: 3 }, e: 4 };

const combinedObj = _.merge({}, obj1, obj2);
console.log(combinedObj);
// Output: { a: 1, b: { c: 2, d: 3 }, e: 4 }

1. The merge() function merges the properties of obj1 and obj2 recursively into a new object.

Choose the method that best suits your requirements and the environment you are working in.
