partialRight

Creates a function that invokes fn with partials appended to the arguments it receives.

Use the spread operator (...) to append partials to the list of arguments of fn.

const partialRight = (fn, ...partials) => (...args) => fn( ...args, ...partials);

function greet(greeting, name) {
  return greeting + ' ' + name + '!';
}
const greetJohn = partialRight(greet, 'John');
greetJohn('Hello'); // 'Hello John!'
