how to use the multiply function from lodash in javascript

To use the multiply function from Lodash in JavaScript, you first need to install Lodash via npm or yarn. Once installed, you can import the multiply function and use it as shown in the following code snippet:

index.tsx
// Importing the multiply function from Lodash
const { multiply } = require('lodash');

// Using the multiply function to multiply two numbers
const product = multiply(2, 3); // Output: 6

In the code above, we first import the multiply function from Lodash by using object destructuring. We then use the multiply function to multiply two numbers and store the result in the product variable.

You can also use the multiply function to multiply an array of numbers or an array of objects by a particular property. For example:

index.tsx
// Multiplying an array of numbers using the multiply function
const arr1 = [2, 4, 6];
const multipliedArr1 = arr1.map(num => multiply(num, 2)); // Output: [4, 8, 12]

// Multiplying an array of objects using the multiply function
const arr2 = [
  { value: 2 },
  { value: 4 },
  { value: 6 }
];
const multipliedArr2 = arr2.map(obj => ({ ...obj, value: multiply(obj.value, 2) }));
/* Output:
[
  { value: 4 },
  { value: 8 },
  { value: 12 }
]
*/

In the code above, we first multiply an array of numbers by 2 using the multiply function along with the map method. We then multiply an array of objects by their value property using the multiply function along with the map and spread syntax.
