JavaScript built-in objects

The short answer The simple answer is: No, there is no generic means to determine that an object is equal to another in the sense you mean . The exception is when you are strictly thinking of an object being typeless.1 Şub 2015

As from The Definitive Guide to Javascript. Objects are not compared by value : two objects are not equal even if they have the same properties and values. This is true of arrays too: even if they have the same values in the same order.

Comparing objects with equals() If the two objects have the same values, equals() will return true . In the second comparison, equals() checks to see whether the passed object is null, or if it’s typed as a different class. If it’s a different class then the objects are not equal.

The referential equality (using === , == or Object.is() ) determines whether the operands are the same object instance . The manual equality check requires a manual comparison of properties’ values.8 Haz 2020
