How would I remove the text from the output of this reduced array

I have an array:
['Online Learning', 'Online Learning', 'Online Learning', 'Communications', 'Communications', 'Intranet']

I’m using the below to find the frequency/occurrences of each value in this array:

const catsReduced = cats.reduce((acc: any, currentValue: any) => (acc[currentValue] = (acc[currentValue] || 0) + 1, acc), {});

This outputs:

{Online Learning: 3, Communications: 2, Intranet: 1}

How would I edit the above reducer to show just:

[3,2,1]

(as number types).
I’m not sure I can be clearer, but please do say if more is required.

>Solution :

Instead of using an object to store the counts, you can directly push the counts into an array.

1- iterate over the array using reduce and count the ocurrences of each element.

2-extract the values (the counts) from the resulting object using Object.values().

3- the resulting array contains the counts of each unique value in the same order they appear in the original array.

const cats = ['Online Learning', 'Online Learning', 'Online Learning', 'Communications', 'Communications', 'Intranet'];

const counts = Object.values(cats.reduce((acc, currentValue) => {
  acc[currentValue] = (acc[currentValue] || 0) + 1;
  return acc;
}, {}));

console.log(counts);

Edit: if typescript is giving you that error try changing your lib compiler option to es2017 or later which can be found probably in your tsconfig.json file

{
  "compilerOptions": {
    "target": "es2017",
    "lib": ["es2017"]
  }
}
