Count frequency of specific value in JavaScript object

Question

I have a JavaScript object that is structured as such:

var subjects = {all: "inactive", firstSingular: "active", secondSingular: "inactive", thirdSingular: "active", firstPlural: "inactive", secondPlural: "inactive", thirdPlural: "inactive"

I would like to count the instances of the "active" value within this object (i.e return 2). I could certainly write a function that iterates through the object and counts the values, though I was wondering if there was a cleaner way to do this (in 1 line) in JavaScript, similar to the collections.Counter function in python.

Answer 1

Another possible solution using filter and getting length of result

var subjects = {all: "inactive", firstSingular: "active",secondSingular:"inactive", thirdSingular: "active", firstPlural: "inactive",secondPlural: "inactive", thirdPlural: "inactive"}

var res = Object.values(subjects).filter((val) => val === 'active').length

console.log(res)
