how to use the indexof function from lodash in javascript

To use the indexOf function from lodash in JavaScript, follow these steps:

1. Install lodash by running npm install lodash command in your terminal.

2. Import lodash in your JavaScript file using the require statement:

index.tsx
const _ = require('lodash');
29 chars
2 lines

3. Declare an array to search for a particular element using the indexOf function:

index.tsx
const arr = [1, 2, 3, 4, 5];
29 chars
2 lines

4. Use the indexOf function from lodash to get the index of the element you are searching for:

index.tsx
const index = _.indexOf(arr, 3);
33 chars
2 lines

In this example, the indexOf function will return the index of the number 3 in the arr array. The resulting value of index will be 2 since 3 is located at the 2nd index in the arr array.

Here's the full code block:

index.tsx
const _ = require('lodash');
const arr = [1, 2, 3, 4, 5];
const index = _.indexOf(arr, 3);
console.log(index); // Output: 2
124 chars
5 lines
