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

To use the restArguments function from the underscore library in TypeScript, follow these steps:

  1. First, make sure you have installed the underscore library using a package manager like NPM or Yarn.

    npm install underscore
    # or
    yarn add underscore

  2. Import the restArguments function from the underscore library.

    index.ts
    import { restArguments } from 'underscore';

    2 lines
  3. Define a function using the restArguments function. The restArguments function takes two arguments: the first is the function to be transformed, and the second is the number of arguments to preserve.

    index.ts
    function myFunction(...args: any[]): void {
      console.log(args);
    }
    
    const myRestFunction = restArguments(myFunction, 2);

    6 lines

    In this example, myRestFunction is a new function that will call myFunction with the first two arguments passed directly and the rest of the arguments passed as an array.

  4. Use the new function as you would any other function.

    index.ts
    myRestFunction(1, 2, 3, 4, 5); // logs [1, 2, [3, 4, 5]]
