How to remove the falsy value attribute from object

Sometimes we want to remove null, empty, undefined, false value attribute from an object. we can do this using the below method.

const removeFalsyElement = object => {
  const newObject = {};
  Object.keys(object).forEach(key => {
    if (object[key]) {
      newObject[key] = object[key];
    }
  });
  return newObject;
};

assume my object like this

const myObject = {
  withValue: "have some value",
  withNumber: 1234,
  nullValue: null,
  undefinedValue: undefined,
  emptyValue: "",
  falseValue: false
};

and want to return those attribute which has actual value.
usage

console.log(removeFalsyElement(myObject));
// output: Object { withValue: "have some value", withNumber: 1234 }

const obj = {
  name: "John Doe",
  age: 30,
  occupation: "Software Engineer",
  hobbies: ["Coding", "Reading", "Hiking"],
  nullKey: null,
  emptyStrKey: ''
};

const newObj = Object.fromEntries(
  Object.entries(obj).filter(([key, value]) => value)
);

console.log(newObj);

Try this:

let output = Object.entries(myObject).reduce((a,[k,v]) => (v == null ? a : (a[k]=v, a)), {});

console.log(output)
