how to use the clone function from the underscore library in javascript

The clone() function from the Underscore library in JavaScript can be used to create shallow clones of objects and arrays. Shallow cloning means that a new object or array is created, and all of its properties or elements are copied by reference instead of by value.

To use the clone() function, start by importing the Underscore library into your JavaScript file. Then, call the clone() function with the object or array that you want to clone as its argument. Here's an example with an object:

index.tsx
const _ = require('underscore');

const originalObject = {
  name: 'Alice',
  age: 30,
  interests: ['reading', 'swimming', 'hiking']
};

const clonedObject = _.clone(originalObject);

console.log(clonedObject);
// Output: { name: 'Alice', age: 30, interests: [ 'reading', 'swimming', 'hiking' ] }
298 chars
13 lines

In this example, we use require() to import the Underscore library into the file. Then, we create an originalObject that contains a name, age, and array of interests. We then call the clone() function from the Underscore library with the originalObject as an argument to make a new clonedObject. Finally, we log the clonedObject to the console to confirm that it has the same properties and elements as the originalObject.

You can use the clone() function with arrays in the same way as objects. Here's an example:

index.tsx
const originalArray = [1, 2, 3, ['a', 'b', 'c']];

const clonedArray = _.clone(originalArray);

console.log(clonedArray);
// Output: [1, 2, 3, ['a', 'b', 'c']]
160 chars
7 lines

In this example, we create an originalArray that contains numbers and an array of characters. We then use the clone() function from the Underscore library to create a clonedArray that we log to the console. The resulting clonedArray is identical to the originalArray in terms of its elements.
