Any Type in TypeScript

Any type is the most flexible type you can assign in TypeScript. This type does not tell TypeScript anything about any type. A variable that is declared using Any type can store any value.

let a: any;

Now a can contain any values. Because of that TypeScript will not throw any error in the below 3 lines of code.

let a: any;
a = 10;
a = "Apple";

any takes away all advantages TypeScript gives you. Therefore, it is not advised to use any data type.
