how to use the _ function from lodash in javascript

You can use the _ function from Lodash in JavaScript by importing it and using it to manipulate arrays or objects. Here's an example of how to use the _ function to sort an array of numbers:

index.tsx
import _ from 'lodash';

const numbers = [5, 3, 8, 1, 9];

const sortedNumbers = _.sortBy(numbers);

console.log(sortedNumbers); // [1, 3, 5, 8, 9]

In this example, we first import the _ function from the Lodash library. We then create an array of numbers and use the sortBy function from Lodash to sort the array. The sorted array is then logged to the console.

You can also use the _ function to manipulate objects. For example, you can use the map function to transform an array of objects into a new array:

index.tsx
import _ from 'lodash';

const users = [
  { id: 1, name: 'Alice' },
  { id: 2, name: 'Bob' },
  { id: 3, name: 'Charlie' }
];

const usersWithIds = _.map(users, user => ({
  ...user,
  userId: `user-${user.id}`
}));

console.log(usersWithIds);
// [
//   { id: 1, name: 'Alice', userId: 'user-1' },
//   { id: 2, name: 'Bob', userId: 'user-2' },
//   { id: 3, name: 'Charlie', userId: 'user-3' }
// ]

In this example, we create an array of user objects. We then use the map function from Lodash to transform the array. The map function takes a function that is applied to each element of the array. In this case, we use an arrow function to add a new property userId to each user object. The ...user syntax is used to copy the existing properties of the user object into a new object, and then we add the new userId property. Finally, the transformed array is logged to the console.
