Any and union type

Any Type

• Any datatype says TypeScript to ignore type check on the variable.
• This means that you can store string, boolean and number in the variable.
• Any can mostly be used in migration project.

Example :

var a : any;
a = 10;
a = true;
a = "Hello World"

Union Type

• Union Type can be used to define multiple data type to a variable.
• This is achieved by using pipe separated data type.
• Below is the example for the same.

var a : number | boolean;
a = 10;
a = true;
