Does this answer your question? [Check if a value is an object in JavaScript](https://stackoverflow.com/questions/8511281/check-if-a-value-is-an-object-in-javascript) – Thanhal P A Jun 17 '22 at 05:04

a = {'a':1,'b':2} result = a instanceof Object && !(a instanceof Array)
result will be true if variable a contains key-value pairs.
- 'a instanceof Object' returns true when a is an array also. That is why the second condition is there.

If you want to know a variable is instance of Object or not, you are be able to easily do this:
if (typeof myVariable === 'object') {
//do something
} else {
//do something
}
