Module partialRight

partialRight

• partialRight<F>(func: F, ...partials: any[]): (...args: any[]) => ReturnType<F>

• Creates a function that invokes func with partials prepended to the arguments it receives. This method is like bind except it does not alter the this binding.

  The partial.placeholder value, which defaults to _ in monolithic builds, may be used as a placeholder for partially applied arguments.

  Note: This method doesn't set the "length" property of partially applied functions.
