JavaScript Code:

//#Source https://bit.ly/2neWfJ2
const over = (...fns) => (...args) => fns.map(fn => fn.apply(null, args));
const minMax = over(Math.min, Math.max);
console.log(minMax(1, 2, 3, 4, 5));
console.log(minMax(1, 2, 5, 4, 3));
console.log(minMax(1, 2, 5, -4, 3));

## JavaScript: Tips of the Day

Chunks an array into n smaller arrays

Example:

const tips_chunkIntoN = (arr, n) => {
const size = Math.ceil(arr.length / n);
return Array.from({ length: n }, (v, i) =>
arr.slice(i * size, i * size + size)
);
}
console.log(tips_chunkIntoN([1, 2, 3, 4, 5, 6, 7,8], 4));

Output:

[[1,2],[3,4],[5,6],[7,8]]
