How does lodash.flowRight work?

lodash.flowRight works by taking a series of functions as arguments and composing them into a new function that applies the functions from right to left. The resulting function takes the same arguments as the first function in the series and passes the result of each function call as the argument to the next function call. The final result is the result of the last function call in the series. lodash.flowRight is useful for composing complex data transformations or functional pipelines, particularly when dealing with multiple functions that need to be applied in a specific order. Note that lodash.flowRight is similar to the lodash.compose function, which composes functions from left to right. However, lodash.flowRight is more useful when working with data transformations that flow from right to left, such as when working with asynchronous data or when processing data in reverse order.

const _ = require("lodash");

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

function square(n) {
  return n * n;
}

function double(n) {
  return n * 2;
}

const composedFunc = _.flowRight(double, square, add);

console.log(composedFunc(2, 3)); // 50

In this example, we have three functions: add, square, and double. We use lodash.flowRight to compose these functions into a new function called composedFunc. When composedFunc is called with two arguments (2 and 3), the add function is called with 2 and 3, and returns 5. The square function is then called with 5 and returns 25. Finally, the double function is called with 25 and returns 50. The resulting value of 50 is the final result of the function composition, which is equivalent to calling double(square(add(2, 3))). Note that lodash.flowRight can be used with any combination of functions that return compatible data types, including functions that return Promises or other asynchronous values.
