Copy a new object in vuejs

In Vue.js, you can create a copy of an object using the Object.assign() method or the spread operator (...).

Method 1: Using Object.assign()

const originalObject = { a: 1, b: 2, c: 3 };
const copiedObject = Object.assign({}, originalObject);

console.log(copiedObject); // Output: { a: 1, b: 2, c: 3 }

Method 2: Using the spread operator (...)

Note: This method is only available in Vue.js 2.3.0 and later versions.

const originalObject = { a: 1, b: 2, c: 3 };
const copiedObject = {...originalObject };

console.log(copiedObject); // Output: { a: 1, b: 2, c: 3 }

Method 3: Using JSON.parse(JSON.stringify())

This method is useful when you need to create a deep copy of an object.

const originalObject = { a: 1, b: { c: 2, d: 3 } };
const copiedObject = JSON.parse(JSON.stringify(originalObject));

console.log(copiedObject); // Output: { a: 1, b: { c: 2, d: 3 } }

Method 4: Using a library like Lodash

If you're using Lodash in your project, you can use the cloneDeep() method to create a deep copy of an object.

const _ = require('lodash');
const originalObject = { a: 1, b: { c: 2, d: 3 } };
const copiedObject = _.cloneDeep(originalObject);

console.log(copiedObject); // Output: { a: 1, b: { c: 2, d: 3 } }

Remember that when you create a copy of an object, you're creating a new reference to the original object. If you modify the copied object, it won't affect the original object.
