This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. With arrow functions, we can define curried functions explicitly, making them easier to understand for other programmers: These explicitly curried arrow functions are particularly important for debugging: If were using a functional library like lodash/fp or ramda, we can also use arrows to remove the need for the auto-curry style: As with currying, we can use arrow functions to make partial application easy and explicit: Its also possible to use rest parameters with the spread operator to partially apply variadic functions: Lodash comes with a number of functions that reimplement syntactical operators as functions, so that they can be passed to collection methods.
