javascript test for an empty object code example

Example 1: check if object is empty javascript

const empty = {};
/* -------------------------
  Plain JS for Newer Browser
----------------------------*/
Object.keys(empty).length === 0 && empty.constructor === Object
// true
/* -------------------------
  Lodash for Older Browser
----------------------------*/
_.isEmpty(empty)
// true

Example 2: javascript test for empty object

// because Object.entries(new Date()).length === 0;
// we have to do some additional check
Object.entries(obj).length === 0 && obj.constructor === Object
