define-property
Advanced tools
The define-property npm package is used to define a new property directly on an object, or modify an existing property on an object, and return the object. It is a convenience wrapper around Object.defineProperty that allows you to easily set configurable, enumerable, and writable property attributes.
Define a new property with default attributes
This feature allows you to define a new property on an object with default attributes. The property will be configurable, enumerable, and writable.
{"object": {"foo": "bar"}, "propertyName": "newProp", "value": 123}Define a new property with custom attributes
This feature allows you to define a new property on an object with custom attributes, such as making the property non-writable.
{"object": {"foo": "bar"}, "propertyName": "newProp", "descriptor": {"value": 123, "configurable": true, "enumerable": true, "writable": false}}This package provides similar functionality to define-property by allowing you to define a new property on an object. It is a direct polyfill for Object.defineProperty, which can be useful for environments that do not support the ES5 method.
While not a direct alternative, property-expr allows you to work with property paths. It can compile strings into functions that can set properties on an object, which can be seen as a more dynamic way to define properties.
Convenience for defining a non-enumberable property on an object.
