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

To use the flowRight function from the Lodash library, you can follow the steps below in TypeScript:

  1. First, install the Lodash library using either npm or yarn:

    npm install lodash
    
    19 chars
    2 lines
    yarn add lodash
    
    16 chars
    2 lines
  2. Next, import the flowRight function from the Lodash library at the top of your TypeScript file:

    index.ts
    import { flowRight } from "lodash";
    
    36 chars
    2 lines
  3. You can now use the flowRight function as follows:

    index.ts
    const add = (a: number, b: number): number => a + b;
    const square = (n: number): number => n * n;
    const subtract = (a: number, b: number): number => a - b;
    
    const result = flowRight(subtract, square, add)(1, 2); // result is -8
    
    228 chars
    6 lines

    In this example, we first define three functions add, square, and subtract. We then use the flowRight function to combine these functions into a single function that will first add two numbers, then square the result, and finally subtract a third number to produce the final result. We call this combined function with the arguments (1, 2) to obtain the final result of -8.
