Then, you can import the flow function and use it in your TypeScript code like this:

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

// Define the functions to be composed
function multiply(a: number, b: number): number {
  return a * b;
}

function add(a: number, b: number): number {
  return a + b;
}

// Compose the functions using `flow`
const multiplyAndAdd = flow([multiply, add]);

// Call the composed function
const result = multiplyAndAdd(2, 3); // returns 5

The flow function takes an array of functions and returns a new function that is the composition of those functions, with the output of each function being passed as input to the next one. In the example above, the mulitplyAndAdd function first multiplies its inputs by 1 and 2, then adds them together, resulting in 5.
