Benchmark: for...in vs Object.keys counting

Script Preparation code:

var obj = {
    'a': true,
    'b': true,
    'c': false,
    'd': true,
    'e': false,
    'f': false,
    'g': true
};

Tests:

for...in : how many true are
for (const key in obj) { const count = 0; if (obj[key]) { count = count + 1 } }
Object.keys : how many true are
Object.keys(obj).forEach(key => { const count = 0; if (obj[key]) { count = count + 1 } })
