how to use the uniq function from the underscore library in typescript

Here's a simple example of how to use the uniq function from the Underscore library in TypeScript:

index.ts
import * as _ from 'underscore';

// define an array with duplicate values
const myArray = [1, 2, 2, 3, 3, 3, 4, 4, 4, 4];

// use the uniq method to filter out duplicate values
const uniqueArray = _.uniq(myArray);

// print the unique values
console.log(uniqueArray); // [1, 2, 3, 4]
285 chars
11 lines

First, we import the underscore library using the import statement. Next, we define an array with duplicate values. Finally, we use the uniq method from the Underscore library to filter out duplicate values and store the result in a new uniqueArray variable. We then print the uniqueArray variable to the console.

Note that we're using TypeScript's import statement to bring in the underscore library, and we're using the * as _ syntax to give us access to all of the functions in the library.
