TypeScript is a flexible option for full-stack development because of its adaptability.  

Examining the Different TypeScript Types  

TypeScript allows programmers to create a wide range of types, from more complex kinds like interfaces and generics to more fundamental types like integer, text, and boolean. Typescript vs JavaScript developers can write more predictable and organized code by using these kinds.  
Examining the Different TypeScript Types  

1. Fundamental Types

– Number: Indicates numerical values, such as floating-point and integer values.  
– String: Denotes textual information surrounded by a single or double quotation.  
Boolean: Indicates whether something is logically true or untrue.  
– Array: Square brackets indicate an array, which is a grouping of items of a certain kind.  
 
2. Complex Categories

– Interfaces: Specifies the types and characteristics of an object form contract.  
– Enums: Makes code easier to comprehend by allowing the construction of a collection of named constants.  
– Generics: Provides reusable, type-safe components that can handle various data types.  
 
3. Union and Intersection kinds

– Union Types: The `|} operator designates a value that can be any of numerous kinds.  
– Intersection kinds: Shown by the `&} operator, these kinds combine many different types.  
 
4. Type-Based Assertions

Assertion Type: enhances type inference by enabling developers to inform the compiler that they are more knowledgeable about a value’s type than TypeScript is.  
 
5. Literal Types

Types of Literals: represents, using certain literal values, a subset of values of a basic data type (string, integer, etc.).  
 
6. Undefined and Null

– Null: Indicates a purposeful lack of any object value.  
Undefined: This denotes a declared variable that is not yet given a value.  

Characteristics that Set TypeScript Apart   

JavaScript is not the same as TypeScript because of its abundance of features. Static typing, classes, modules, decorators, and sophisticated tooling support are a few noteworthy characteristics. JavaScript vs typescript codebases with these qualities are easier to manage and the development process runs more smoothly.
