you can slice an object using the slice() method. The slice() method creates a shallow copy of a portion of an array or object.

Here's an example:

const originalObject = {a: 1, b: 2, c: 3, d: 4};
const slicedObject = Object.slice(originalObject, 1, 3);

Resulting slicedObject will be: {b: 2, c: 3}.

Note that Object.slice() only creates a shallow copy, meaning that any changes made to the sliced object will also affect the original object. If you want a deep copy, you can use a library like lodash or a custom implementation.
