lodash.set

What is lodash.set?

The lodash.set package is a method from the Lodash library that allows users to set the value at a given path of an object. It can create nested objects if the path does not exist and can handle array indexes within the path.

What are lodash.set's main functionalities?

Set property value on object

Sets the value of property 'c' to 4 in the object at the path 'a.b.c'.

{"object": {"a": {"b": {"c": 3}}}, "path": "a.b.c", "value": 4}

Create nested objects

Creates a nested structure within the object if it does not exist and sets the value at the specified path.

{"object": {}, "path": "a[0].b.c", "value": 4}

Handle array indexes

Sets the value at a path that includes an array index, modifying the existing array element.

{"object": {"a": [{"b": {"c": 3}}]}, "path": "a[0].b.c", "value": 4}

Other packages similar to lodash.set

dot-prop

The dot-prop package allows users to get, set, or delete properties from a nested object using a dot path. Unlike lodash.set, dot-prop does not depend on the full Lodash library and is a smaller package focused on property manipulation.

deepdash

Deepdash is an extension for Lodash that adds deep object manipulation capabilities. It offers similar functionality to lodash.set but with additional methods for deep traversal and manipulation of objects and arrays.

object-path

Object-path is another utility that provides a simple way to get and set deep values in an object using a string path. It is similar to lodash.set but is a standalone package that does not rely on Lodash.
