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

To use the rest function from the Underscore library in TypeScript, first you need to install the Underscore library using npm. You can do this by running the following command in your terminal:

index.ts
npm install underscore --save
30 chars
2 lines

Then, you need to import the Underscore library at the top of your TypeScript file like this:

index.ts
import * as _ from 'underscore';
33 chars
2 lines

After that, you can use the rest function as follows:

index.ts
function myFunc(firstArg: string, ...restArgs: string[]) {
  // Use the rest function from Underscore
  const firstRestArg = _.rest(restArgs);
  console.log(firstRestArg);
}

myFunc('first', 'second', 'third', 'fourth');
221 chars
8 lines

In this example, the rest function is used to extract all arguments except the first one. The output of this code snippet will be:

index.ts
['second', 'third', 'fourth']
30 chars
2 lines

which shows that the rest function has successfully extracted the rest of the arguments.
