In JavaScript, null represents intentional absence of any object value, undefined represents the absence of any value, and 0 represents the integer zero. To differentiate between them, you can use the triple-equals (===) operator, which compares both the value and data type. The double-equals (==) operator performs type coercion and is not recommended for type-safe comparisons.

Null in JavaScript means an empty value and is also a primitive type in JavaScript. The variable which has been assigned as null contains no value. Undefined, on the other hand, means the variable has been declared, but its value has not been assigned.
