Undefined value
It is not a value for assignments. It indicates that a variable has been declared but not yet given a value. It is itself a type. When a variable has not been given a value, the primitive value undefined is utilised. Undefined implies that the variable is not present.
Null
It is a value for an assignment. It can be set to a variable to show that it does not point at anything. It is a thing. The primitive value known as "null" stands for a null, empty, or non-existent reference. A variable's null value denotes the absence of a value.
