How to sum the values of a JavaScript object?

Question

I\'d like to sum the values of an object.

I\'m used to python where it would just be:

sample = { \'a\': 1 , \'b\': 2 , \'c\':3 };
summed =  sum(sampl         


        

Answer 1

We can iterate object using in keyword and can perform any arithmetic operation.

// input
const sample = {
    'a': 1,
    'b': 2,
    'c': 3
};

// var
let sum = 0;

// object iteration
for (key in sample) {
    //sum
    sum += (+sample[key]);
}
// result
console.log("sum:=>", sum);
