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

To use the wrap function from the Underscore library in TypeScript, you will need to install the type definitions for Underscore. You can do this by running the following command in your terminal:

index.ts
npm install --save-dev @types/underscore

2 lines

Once you have installed the type definitions, you can import the wrap function from Underscore and use it like this:

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

const wrappedFunc = wrap((text: string) => {
  return text.toUpperCase();
}, (func, text) => {
  return `<p>${func(text)}</p>`;
});

const wrappedText = wrappedFunc('hello world');
console.log(wrappedText); // <p>HELLO WORLD</p>

In this example, we are wrapping a function that uppercases the input text and returning it in an HTML paragraph tag. The wrap function takes the original function as its first argument and a wrapper function as its second argument. The wrapper function takes the original function and its input arguments as its arguments and returns the wrapped result.

By using wrap from Underscore, we can easily create a new wrapped function that maintains the original functionality while adding additional processing to the result.
