30秒学会 JavaScript 片段 – Append function arguments

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.

代码实现

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

const greet = (greeting, name) => greeting + ' ' + name + '!';
const greetJohn = partialRight(greet, 'John');
greetJohn('Hello'); // 'Hello John!'
