API

defaults(options, defaultOptions?)

Deeply merges the given options with the specified defaults and returns a new object.

The given parameters are deep-cloned and never mutated.

options

Type: object

The user-provided options.

If the value is not a plain object, a new plain object will be used instead.

defaultOptions

Type: object | undefined

The default options to use when a value is not provided in the options object.

FAQ

Why use this over object-spread?

  • Does not overwrite options if they are not defined in the options object
  • Supports deep merging of objects
  • Provides protection against prototype pollution attacks
