Implement your own myreduce method which returns the sum of an array.
You must not create a separate function for myreduce.
You must use prototyping for implementation.
Sample of reduce method:
const array1 = [1, 2, 3, 4];
const reducer = function(accumulator, currentValue){return accumulator + currentValue;}
// 1 + 2 + 3 + 4
console.log(array1.reduce(reducer));
// expected output: 10
// 5 + 1 + 2 + 3 + 4
console.log(array1.reduce(reducer, 5));
// expected output: 15Input Format
