Count the number of true members in an array of boolean values

Question

Seems like your problem is solved already, but there are plenty of easier methods to do it.

Excellent one:

.filter(Boolean); // will keep every truthy value in an array

const arr = [true, false, true, false, true];
const count = arr.filter(Boolean).length;

console.log(count);

const arr = [true, false, true, false, true];
const count = arr.filter((value) => value).length;

console.log(count);

let myCounter = 0;

[true, false, true, false, true].forEach(v => v ? myCounter++ : v);

console.log(myCounter);
