I need the sum total of the object, where, but the maximum of each similar pair javascript
var score = {
"work_1": 5,
"work_1|pm": 10,
"work_2": 8,
"work_2|pm": 7
"work_3": 10
};
the work_3 doesn't have a pair similar I wish this result
total = 28
Group the maximums by key-prefix in a new object, and then sum the values of that object. In both phases you can use reduce:
var score = {
"work_1": 5,
"work_1|pm": 10,
"work_2": 8,
"work_2|pm": 7,
"work_3": 10
};
var result = Object.values(
Object.entries(score).reduce((acc, [k, v]) => {
k = k.split("|")[0];
acc[k] = Math.max(v, acc[k] ?? v);
return acc;
}, {})
).reduce((a, b) => a + b, 0);
console.log(result);You can get the property values of the object with Object.values, sort the resulting array, then sum the first 2 items:
var score = {
"work_1": 5,
"work_1|pm": 10,
"work_2": 8,
"work_2|pm": 7,
"work_3": 10
};
const max2 = Object.values(score).sort().splice(0, 2)
const result = max2[0] + max2[1];
console.log(result)
