Answer / Sandeep Kumar Sharma
In JavaScript, both 'undefined' and 'null' are used to represent absence of a value or an empty value. However, they have some differences:nn- 'undefined' represents a variable that has been declared but not assigned a value.n- 'null' is explicitly used to indicate no value or an intentional absence of any object value.nn```javascriptnlet myVar;nconsole.log(myVar); // outputs: undefinednlet myNull = null;nconsole.log(myNull); // outputs: null```
