Data types in TypeScript

In TypeScript, a data type defines the kind of values a variable can hold, ensuring type safety and enhancing code clarity.

• Primitive Types: Basic types like number, string, boolean, null, undefined, and symbol.
• Object Types: Complex structures including arrays, classes, interfaces, and functions.

Primitive Types

Primitive types are the most basic data types in TypeScript. They represent simple, immutable values and are directly assigned.

Object Types

Object types are more complex structures that can contain multiple values and functions. They are mutable and can be manipulated after creation.

Advanced Types

TypeScript also offers advanced types that provide additional capabilities for complex type definitions:

Best Practices of Using Data types in TypeScript

• Use let and const Instead of var: Prefer let and const for block-scoped variables to avoid issues with hoisting and scope leakage.
• Avoid the any Type: Refrain from using any as it bypasses type checking; opt for specific types to maintain type safety.
• Leverage Type Inference: Allow TypeScript to infer types when possible, reducing redundancy and enhancing code readability.
• Utilize Utility Types: Employ built-in utility types like Partial<T> and Readonly<T> to create flexible and readable type definitions.
