I have an array
const sampleObject = {Color: "Blue", Size: "39, 41"}
Using Lodash's _.filter when I try
_.filter(sampleObject, (entry) => entry !== 'Blue')
I get
['39, 41']
But my desired result is
{Size: '39, 41'}
const sampleObject = { Color: "Blue", Size: "39, 41" } const filtered = _.filter(sampleObject, (entry) => entry !== 'Blue') console.log(filtered);

Are you looking for _.pickBy()
?
const sampleObject = { Color: "Blue", Size: "39, 41" } const filtered = _.pickBy(sampleObject, (value,key) => value !== 'Blue') console.log(filtered);

Seems odd you need to do this, but you can use fromEntries and entries to do it
const sampleObject = {Color: "Blue", Size: "39, 41"} const result = Object.fromEntries(Object.entries(sampleObject).filter(x => x[1] !== 'Blue')); console.log(result);
If you want just that one property in a new object, grab it directly:
const sampleObject = {Color: "Blue", Size: "39, 41"}; const result = {Size: sampleObject.Size}; console.log(result);
Or if you need the key to be dynamic:
const sampleObject = {Color: "Blue", Size: "39, 41"}; const key = "Size"; const result = {[key]: sampleObject[key]}; console.log(result);
