Like _.flow, but invokes the given functions from right to left (compose style). Part of Lodash Util since 3.0.0 (stable — not deprecated).
Note: Only the rightmost function receives all outer arguments. Steps to its left get one value — the previous return.
Call _.flowRight. Start with this line.
_.flowRight([funcs]) or _.flowRight(f, g, …)| Call | What it does |
|---|---|
_.flowRight([funcs]) or _.flowRight(f, g, …) | Primary signature. |
_.flowRight(...) | Call the util helper. |
Prefer import flowRight from "lodash/flowRight" when you want a smaller bundle.
_.flowRight([funcs]) or _.flowRight(f, g, …)| Parameter | Description |
|---|---|
| funcs | Optional. Functions to invoke (array and/or rest args) |
| Return Value | Description |
|---|---|
| * | New composite function |
List square then _.add — runtime still runs add first.
function square(n) {
return n * n;
}
var addSquare = _.flowRight([square, _.add]);
addSquare(1, 2);
// → 9[square, _.add] left to right._.add(1, 2) → 3.square(3) → 9._.flow([_.add, square])(1, 2).Same compose without wrapping functions in an array.
function square(n) {
return n * n;
}
var addSquare = _.flowRight(square, _.add);
addSquare(1, 2);
// → 9square, then _.add on the right._.flowRight([square, _.add]).9 for (1, 2).Rightmost runs first: trim, then uppercase.
var clean = _.flowRight(_.toUpper, _.trim);
clean(" hello ");
// → "HELLO"_.trim(" hello ") → "hello"._.toUpper("hello") → "HELLO"._.flow(_.trim, _.toUpper) lists steps in run order.flowRight vs flowSame unary list — opposite invoke order and different results.
function addOne(n) {
return n + 1;
}
function double(n) {
return n * 2;
}
_.flowRight(addOne, double)(3);
// → 7 // (3 * 2) + 1
_.flow(addOne, double)(3);
// → 8 // (3 + 1) * 27.8.flowRight; pipeline reading → flow.Extra arguments reach only the function that runs first (rightmost).
function joinPair(a, b) {
return a + "-" + b;
}
var shout = _.flowRight(_.toUpper, joinPair);
shout("hi", "there");
// → "HI-THERE"joinPair("hi", "there") → "hi-there"._.toUpper receives that one string._.partial._.flowRight is a Lodash Util helper since 3.0.0. It runs anywhere Lodash runs — modern browsers (CDN or bundle) and Node.js / Bun / Deno with npm install lodash.
Available in [email protected] full builds and the lodash/flowRight modular import. Works in evergreen browsers and current Node LTS when Lodash is installed.
Bottom line: Safe for production once Lodash is loaded. Prefer import flowRight from "lodash/flowRight" for smaller bundles. Use it when compose (right-to-left) reading matches how you think about the transform.
Return the first argument unchanged — a no-op building block.
