Modules

JavaScript is a powerful and dynamic language. With dynamic programming in JavaScript, we need to structure and organize the code so that it will make its maintainability easier and also enable us to easily locate the code for a specific functionality. We can organize code by applying a modular pattern. Code can be separated into various modules, and relevant code can be put in each module.

TypeScript made it easier to implement modular programming using the module keyword. Modules enable you to control the scope of variables, code reusability, and encapsulation. TypeScript supports two types of module: internal and external modules.
