TypeScript Basics

1. What is TypeScript?

• A superset language of JavaScript developed by Microsoft

• A language developed by adding features like static type checking and class-based object-oriented programming to JavaScript

2. Background of TypeScript's Emergence

• JavaScript was initially created as a scripting language that only worked in browsers, but as web application interactions using JavaScript increased, the amount of JavaScript code needed exploded

• JavaScript has the advantage of being flexible with dynamic typing and being able to use various libraries and frameworks, but has the disadvantage of lacking type explicitness

• Lack of type explicitness leads to unexpected results

3. Advantages of Using TypeScript

• TypeScript provides static type checking functionality and improves code readability and maintainability

• This allows developers to minimize runtime errors, reduce code writing time, and improve code readability during collaboration

• Additionally, TypeScript supports the latest JavaScript syntax including ES6 syntax, and provides features like Interfaces, Generics, Decorators, etc., making object-oriented programming easier
