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)

dmikester1•11mo ago

aw, ok, what does 'length' do?

ScriptyChris•11mo ago

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

dmikester1•11mo ago

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 😅
