JavaScript: Create a function that invokes each provided function with the arguments it receives and returns the results

JavaScript fundamental (ES6 Syntax): Exercise-36 with Solution

Write a JavaScript program to create a function that invokes each provided function with the arguments it receives and returns the results.

  • Use Array.prototype.map() and Function.prototype.apply() to apply each function to the given arguments.

Sample Solution:

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));

Sample Output:

[1,5]
[1,5]
[-4,5]

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]]
