let a: null = null;
let b: number = 123;
let c: number = 123.456;
let d: string = ‘Geeks’;
let e: undefined = undefined;
let f: boolean = true;
let g: number = 0b111001; // Binary
let h: number = 0o436; // Octal
let i: number = 0xadf0d; // Hexa-Decimal
In built-in data types, any is a special data-type, also the super data-type of all data types. If a variable is declared with any data type then we can assign any type value to that variable.
Examples:
let a: any = null;let b: any =123;
let c: any = 123.456;
let d: any = ‘Geeks’;
let e: any = undefined;
let f: any = true;
let dynamicList: any[] = [ "Kunal Chowdhury",
"Free User",
21,
true
];

Array types can be written in one of two ways. In the first, you use the type of the elements followed by [] to denote an array of that element type:
Tryletlist : number[] = [1, 2, 3];
The second way uses a generic array type, Array<elemType>:
letlist :Array <number> = [1, 2, 3];-------------------------------------------------let firstName: string = "Kunal"; let lastName: string = "Chowdhury";let message: string = `Hi, my name is: ${firstName} ${lastName}`; let spannedMessage: string = `Hi, My name is: ${firstName} ${lastName}`;let dynamicValue: any = "Kunal Chowdhury";By default, the enum values start from 0 (zero), but you can also set it by manually entering the value of its members. Consider the following two examples:
1enum CardTypes { Debit = 1, Credit, Virtual }
