Filter an object which contains values of zero

I am having a little bit of trouble of trying to filter out data that does not contain zero.

for example:

const height = {
  cm: 0,
  feet: 10,
  inches: 5,
}

and the desired result is to remove elements that dont have zero.

so desired result is:

const height = {
  feet: 10,
  inches: 5,
}

i have tried

    const boo = Object.keys(height).filter((e) => height[e] > 0);

but no luck.

ANy ideas

Object.keys(height).forEach(key => {
    if (height[key] === 0) {
        delete height[key]
    }
})

You could iterate the entries and delete unwanted keys.

const height = { cm: 0, feet: 10, inches: 5 };

Object.entries(height).forEach(([k, v]) => {
    if (v === 0) delete height[k];
});

console.log(height);

Another approach creates a new object without unwanted parts.

const
    height = { cm: 0, feet: 10, inches: 5 },
    result = Object.fromEntries(Object
        .entries(height)
        .filter(([k, v]) => v !== 0)
    );

console.log(result);
