Intersection Types
An intersection type creates a new type by combining multiple existing types. The new type has all features of the existing types.
To combine types, you use the & operator as follows:
type typeAB = typeA & typeB;The typeAB will have all properties from both typeA and typeB.
Note that the union type uses the | operator that defines a variable which can hold a value of either typeA or typeB
