The wrapper version of _.reverse. Reverses the wrapped array and returns a Lodash wrapper. Part of Lodash Seq (since 0.1.0).
Call it on a Lodash wrapper. Finish with .value() when you need a plain result.
Call _.prototype.reverse(). Start with this line.
wrapper.reverse()| Call | What it does |
|---|---|
wrapper.reverse() | Primary signature. |
Prefer import _ from "lodash" (full build) when you need wrapper prototype helpers.
wrapper.reverse()| Parameter | Description |
|---|---|
| Receiver | Required. A Lodash wrapper around an array |
| Return Value | Description |
|---|---|
| * | New wrapper; array mutated on flush |
Reverse a wrapped array and unwrap.
var array = [1, 2, 3];
_(array).reverse().value();
// → [3, 2, 1]_(array) creates a Seq wrapper..value() returns [3, 2, 1].The same array object is reversed in place.
var array = [1, 2, 3];
_(array).reverse().value();
JSON.stringify(array);
// → "[3,2,1]"array.array shows [3, 2, 1].Mutation may wait until .value() or .commit().
var array = [1, 2, 3];
var wrapped = _(array).reverse();
JSON.stringify(array);
// → "[1,2,3]" (often still original)
wrapped.value();
JSON.stringify(array);
// → "[3,2,1]".reverse() is pending on the wrapper.array may still show the old order..value() applies the reverse..commit() to apply early and keep chaining.Keep the original order by wrapping a shallow copy.
var array = [1, 2, 3];
_(array.slice()).reverse().value();
// → [3, 2, 1]
JSON.stringify(array);
// → "[1,2,3]" (original untouched)array.slice() makes a new array.array stays [1, 2, 3].Combine transforms in one chain.
_(["a", "b", "c"])
.map(function (s) { return s.toUpperCase(); })
.reverse()
.value();
// → ["C", "B", "A"]["A","B","C"].["C","B","A"]..value() returns the plain array.map are new — mutation hits that result, not your source literals in the same way as wrapping an existing variable.Wrapper .reverse() is a Lodash Seq prototype method (since 0.1.0). It relies on array reverse semantics and needs no special browser APIs beyond loading Lodash.
Available in [email protected] full builds when using _(value) / _.chain(value). Works in evergreen browsers and Node / Bun / Deno when Lodash is installed.
Bottom line: Safe for production once Lodash is on the page or in your bundle. Prefer the full lodash build for Seq / wrapper APIs.
Execute the chain and unwrap to plain JavaScript data.
