For developers that are accustomed to Object Oriented paradigm, traditional JavaScript programming poses a challenge. Non object oriented code is difficult to manage and the complexity only grows as the size of the project.
This is where Typescript wins over JavaScript. TypeScript is an open source syntactic superset of JavaScript that compiles to JavaScript (EcmaScript 3+). It uses all the code found in JavaScript with other coding concepts such as classes, modules, interfaces, and types.
It was created to make JavaScript development easier.
TypeScript offers type annotations which provide optional, static type checking at compile time. Since it is a superset of JavaScript, all JavaScript is syntactically valid TypeScript.
Other advantages of Typescript include:
- TypeScript has code completion and IntelliSense.
- Types can be added to variables, functions, properties, etc. This helps the compiler and flags warnings about potential errors in code before an app is ever run.
- Supports Generics & Modules.
- TypeScript’s tooling is fantastic.
TypeScript is becoming a tool of choice for organizations that have large projects to manage. The structure of the object-oriented programming language keeps the code clean, consistent, and simple to debug.
