Example of the Typescript language

Javascript
// addNumbers.ts 
  
// Function to add two numbers 
function addNumbers(a: number, b: number): number { 
  return a + b; 
} 
  
// Variables representing two numbers 
let num1: number = 5; 
let num2: number = 8; 
  
// Call the function and store the result 
let sum: number = addNumbers(num1, num2); 
  
// Output the result to the console 
console.log(`The sum of ${num1} and ${num2} is: ${sum}`); 

Output:

The sum of 5 and 8 is: 13

Features of the Typescript Language

It provides support for static typing and specific item-oriented language capabilities such as limitations, inheritance, interfaces, and names.TyрeScript can be applied to existing JavaScript code, contains popular JavaScript libraries, and interacts with TypeScript generated code from other JavaScript. TypeScript is a language extension that adds capabilities to ECMAScript with additional features: type annotations and compile-time type checking, type inference, type erаsure, interfaces, enumerated types, generics, tuples, namespaces, async/await.Modules, Classes, Аbbreviated “arrow” syntax fоr the anonymous functions, default parameters, and optional parameters are among the features backported from ECMAScript 2015....

Advantages of the Typescript

Code quality: Defining data structures in the beginning, using types and interfaces, forces you to think about your app’s data structure from the start and make better design decisions.Prevents bugs: TypeScript will not make your software bug-free. However, it can prevent a large number of type-related errors. Along with Clever IntelliSense, many browsers and IDEs enable direct debugging via Source Maps.Active community: TypeScript is becoming increasingly popular. It is used by top tech companies such as Google, Airbnb, Shopify, Asana, Adobe, and Mozilla, so we can assume that it meets their scalability requirements, as they develop large and complex applications....

Conclusion

In conclusion, since its introduction in 2012, TypeScript has developed to include important features like tuples, generics, and null prevention. It prioritises code reliability and developer efficiency with compatibility across multiple IDEs. Custom JSX factories were added in Version 4.0, demonstrating TypeScript’s dedication to innovation. Being a dynamic language, TypeScript is still essential to modern web development because it gives programmers the tools they need to build reliable and maintainable applications in the rapidly evolving tech sector....
