Built-in Type Primitives

TypeScript has several built-in type primitives that can be used to define variables, function parameters, and return types:

• number: Represents numeric values, including integers and floating-point numbers.
• string: Represents textual data
• boolean: Represents logical values, which can be either true or false.
• null: Represents the absence of a value.
• undefined: Represents a value that has not been assigned or has not been defined.
• symbol: Represents a unique identifier. Symbols are typically used as keys for object properties.
• bigint: Represents arbitrary-precision integers.
• any: Represents a dynamic or unknown type. Variables of type any can hold values of any type, and they bypass type checking.
• void: Represents the absence of any type. It is commonly used as the return type of functions that do not return a value.
• never: Represents a type for values that never occur. It is typically used as the return type of functions that throw an error or enter an infinite loop.
