I have an array of objects like below:

var array =

    [

        {name:abc,age:20}

        {name:abc,age:20}

        {name:abc,age:20}

        {name:xyz,age:21}

        {name:xyz,age:21}

    ]

I want to count the number of occurrences of distinct values like:

[3,2]

Assuming abc has 3 occurrences and xyz has 2 occurrences.

I am doing it in reactjs. I am able to get distinct values like [abc,xyz] using this answer.

_{ES6 syntax is preferred.}
