how to use the filter function from lodash in javascript

To use the filter function from lodash library in JavaScript:

  1. Install lodash package using npm or yarn: npm install lodash or yarn add lodash
  2. Import filter function from lodash: const { filter } = require('lodash') or import { filter } from 'lodash'
  3. Invoke filter function with an array as the first argument and a predicate function as the second argument:
index.tsx
const users = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Carl', age: 35 }
]

const filteredUsers = filter(users, (user) => user.age >= 30)
// [{ name: 'Bob', age: 30 }, { name: 'Carl', age: 35 }]
224 chars
9 lines

In the example above, filter function is used to select users whose age is greater than or equal to 30. The second argument is a predicate function that takes each element of the array as an argument and returns a boolean value indicating whether the element should be included in the result.
