var items = ["one", 32, true, "two", 33.1, 45, "world", false];

program in JS that gives the total of summation for numbers only.

In this case, it will add only 32, 33.1 and 45 as an example and should not try to add when it gets non numeric item.

Hint:

var total = 0;

for (var i = 0 ; i < items.length ; i++) {

if (typeof items[i] === 'number') {

//your code here to accumulate the summation on total

}

}
