Filtering object properties based on value

Question

Is there some elegant way of filtering out falsey properties from this object with lodash/underscore? Similar to how _.compact(array) removes falsey elements fr

Answer 1

Another approach

const objFilter = (obj, condition) => {
    let newObj = {}
    for (const [key, value] of Object.entries(obj)) {
        if (condition(value)) {
            newObj = { ...newObj, [key]: value }
        }
    }
    return newObj
}

Fire like this:

const newData = objFilter(oldData, (value) => value.marked === false)
