JavaScript: Tips of the Day

Creates a function that accepts up to n arguments, ignoring any additional arguments

Example:

const ary = (fn, n) => (...args) => fn(...args.slice(0, n));
const tips_firstTwoMax = ary(Math.max, 2);
console.log([[3, 5, 'p'], [4, 8, 12], [15]].map(x => tips_firstTwoMax(...x)));

Output:

[5,8,15]
