flowRight
Creates a new function that executes the given functions in sequence from right to left. The return value of the previous function is passed as an argument to the next function.
The this
context of the returned function is also passed to the functions provided as parameters.
This method is like flow, except that it creates a function that invokes the given functions from right to left.
Signature
typescript
function flowRight<R>(f: () => R): () => R;
function flowRight<A extends any[], R>(f1: (...args: A) => R): (...args: A) => R;
function flowRight<A extends any[], R1, R2>(f2: (a: R1) => R2, f1: (...args: A) => R1): (...args: A) => R2;
function flowRight<A extends any[], R1, R2, R3>(
f3: (a: R2) => R3,
f2: (a: R1) => R2,
f1: (...args: A) => R1
): (...args: A) => R3;
function flowRight<A extends any[], R1, R2, R3, R4>(
f4: (a: R3) => R4,
f3: (a: R2) => R3,
f2: (a: R1) => R2,
f1: (...args: A) => R1
): (...args: A) => R4;
function flowRight<A extends any[], R1, R2, R3, R4, R5>(
f5: (a: R4) => R5,
f4: (a: R3) => R4,
f3: (a: R2) => R3,
f2: (a: R1) => R2,
f1: (...args: A) => R1
): (...args: A) => R5;
function flowRight(...funcs: Array<(...args: any[]) => any>): (...args: any[]) => any;
Parameters
funcs
(Array<(...args: any[]) => any>
): The functions to invoke.
Returns
((...args: any[]) => any
): The new composite function.
Examples
typescript
const add = (x: number, y: number) => x + y;
const square = (n: number) => n * n;
const combined = flowRight(square, add);
console.log(combined(1, 2)); // => 9
Lodash Compatibility
Import flowRight
from es-toolkit/compat
for full compatibility with lodash.
flowRight
can accept both arrays of functions and individual functions as arguments.flowRight
will throw an error if any of the functions provided are not functions.
typescript
import { flowRight } from 'es-toolkit/compat';
const add = (x: number, y: number) => x + y;
const square = (n: number) => n * n;
const double = (n: number) => n * 2;
const combined = flowRight(double, [square, add]);
console.log(combined(1, 2)); // => 18
