Is there an easy way to filter this array by truthy values?

const typesArr = [
{ standard: true },
{ "major-retail": true },
{ "minor-retail": false },
{ mini: false },
{ "greens-grade": false },
{ "ice-melt": true }
];

const typesArr = [
{ standard: true },
{ "major-retail": true },
{ "minor-retail": false },
{ mini: false },
{ "greens-grade": false },
{ "ice-melt": true }
];

Maybe I should change my objects to look like: {type: 'standard', value: true} ?

Makes sense, thank you!

Like that typesArr.filter(Boolean)? Oh, wait there are objects

typesArr.filter(obj => Object.values(obj).filter(Boolean).length)

typesArr.filter(obj => Object.values(obj).filter(Boolean).length)

aw, ok, what does 'length' do?

length prop returns the length of array and if it is empty, length returns 0 and filter would skip that element from output array

oh interesting, that is cool way to do it! Never would have thought of that, thanks!

Why only check for 1 prop, when there is no certainty that other props may be truthy/falsy 🤔 I mean, it depend on the input structure

Okay, fair point. I've hoped that was only an example and final data is bigger 😅
