How to remove undefined and null values from an object using lodash?

Question

I have a Javascript object like:

var my_object = { a:undefined, b:2, c:4, d:undefined };

How to remove all the undefined properties? False

Answer 1

Taking in account that undefined == null we can write as follows:

let collection = {
  a: undefined,
  b: 2,
  c: 4,
  d: null,
}

console.log(_.omit(collection, it => it == null))
// -> { b: 2, c: 4 }
