TypeScript is an open-source programming language developed and maintained by Microsoft. It is a superset of JavaScript, meaning that all valid JavaScript code is also valid TypeScript code. The primary addition TypeScript brings to JavaScript is static typing

Key characteristics :

• Static Typing : Unlike JavaScript, where variable types are determined at runtime (dynamic typing), TypeScript allows developers to explicitly define the types of variables, function parameters, and return values during development. This enables the TypeScript compiler to perform type checking before the code is executed.
• Early Error Detection : By adding static typing, TypeScript can catch common programming errors related to incorrect data types during the compilation phase, rather than at runtime. This leads to more robust and reliable applications and a more efficient development process.
• Transpilation to JavaScript : Browsers and Node.js environments do not directly execute TypeScript code. Instead, TypeScript code is transpiled (converted) into standard JavaScript, which can then run in any JavaScript environment.
• Widely Adopted : TypeScript is widely used in modern web development, particularly with popular frameworks like Angular, React, and Vue.js, and is favored for building scalable and maintainable applications.
