Currified function that multiples array elements in JavaScript
Problem
We are required to write a JavaScript function that takes in an array and returns another function which in turn takes in a number which returns a new array which is the product of corresponding elements of the input array to the first function and the number provided to the second function.
Example
Following is the code −
const arr = [2, 5, 2, 7, 8, 4];
const num = 4;
const produceWith = (arr = []) => (num) => {
const res = arr.map(el => {
return el * num;
});
return res;
};
console.log(produceWith(arr)(num));Output
Following is the console output −
[ 8, 20, 8, 28, 32, 16 ]
