how to use the flip function from the lodash library in typescript

To use the flip function from the Lodash library in TypeScript, you need to install the Lodash library and its type definitions. You can do this by running the following command in your command line:

npm install lodash @types/lodash --save

Once you have installed the library and its type definitions, you can import and use the flip function like this:

index.ts
import { flip } from 'lodash';

function subtract(a: number, b: number): number {
  return a - b;
}

const flippedSubtract = flip(subtract);

console.log(subtract(5, 3)); // Output: 2
console.log(flippedSubtract(5, 3)); // Output: -2

In the example above, we first import the flip function from the lodash library. We then define a function subtract that subtracts the second argument from the first argument. We then create a new function flippedSubtract by passing subtract to the flip function. This new function will subtract its first argument from its second argument instead. Finally, we test both functions to make sure they work as expected.

Note that TypeScript will automatically infer the types of the arguments and return value of the flip function, based on the types of the input and output functions you pass to it.
