can-key/set/set

  • Edit on GitHub

Set properties on deep/nested objects of different types: Object, Map, can-reflect types, etc.

set(object, path, value)

Parameters

  1. object {Object}:

    The object to use as the root for property-based navigation.

  2. path {String}:

    A String of dot-separated keys, representing a path of properties.

  3. value {*}:

    The new value to be set at the property path.

Returns

{*}:

The object passed to set (for chaining calls).

A path is a dot-delimited sequence of one or more property names, such that "foo.bar" means "the property 'bar' of the object at the property 'foo' of the root."

import set from "can-key/set/set";

const object = {a: {b: {c: "foo"}}};
set(object, "a.b.c", "bar");
// Now object.a.b.c === "bar"

var map = new Map();
map.set("first", {second: "third"});

set(map, "first.second", "3rd");
// Now map.first.second === "3rd"

Note: an error will be thrown if one of the objects in the key path does not exist.
