What is d?

The 'd' npm package is a utility for defining property descriptors for JavaScript objects. It is often used to create properties with specific characteristics such as being non-enumerable, writable, or configurable, and can be used in object property definition contexts where you want more control over how properties behave.

What are d's main functionalities?

Defining non-enumerable properties

This code sample demonstrates how to define a non-enumerable property 'foo' with the value 'bar'. The property will not show up in for-in loops or Object.keys() calls.

{"foo": d('bar')}

Defining writable and configurable properties

This code sample shows how to define a property 'foo' that is both writable and configurable with the value 'bar'. This means the property value can be changed and the property descriptor can be modified after the initial definition.

{"foo": d(true, 'bar')}

Defining a getter and setter

This code sample illustrates defining a property 'foo' with a getter and setter function. The getter function returns the value of '_foo', and the setter function assigns the new value to '_foo'.

{"foo": d.gs(function() { return this._foo; }, function(value) { this._foo = value; })}
