Multiply all elements in array

Question

I couldn\'t find an example here what I\'m really looking for. I\'d like to multiply all array elements, so if an array contains [1,2,3] the sum would be 1*2*3=6; So far I\'

Answer 1

The reduce() method executes a provided function for each value of the array and reduces the array to a single value

    const arr = [1,2,3];
    const sum = arr.reduce((prevValue,curValue) => {
        return prevValue * curValue
    },1);
    console.log(sum);

prevValue is the initial value and it's equal 1 in this example

curValue is the value of the current element in array
