The question refers to these advanced features and asks which one is not backported to TypeScript. The correct answer is "Methods."
"Methods" in TypeScript refer to functions that are associated with a particular object. They are another way to include behaviour as part of a data structure, providing a clear way to perform actions that directly relate to the object.
Arrow functions (=>) in TypeScript are much like lambdas in other languages, capturing the
this keyword from the surrounding code.
Classes in TypeScript are an enhancement of ES6/ES2015 classes, providing a cleaner syntax for object-oriented programming and encapsulating data and behaviour into reusable constructs.
Finally, modules in TypeScript are an extension of ES6 modules, allowing developers to split code into separate, reusable parts which can be imported and exported from one another.
TypeScript has provided developers with a set of powerful tools to write safe, robust, and maintainable code. However, it's crucial to maintain good practices, such as proper use of types, relevant usage of classes and interfaces, and avoiding the use of
any type as much as possible.
To go a step further, developers can make use of TypeScript's strict mode, which applies a stricter set of type checking rules and helps catch more potential issues during compile-time, making your code even safer and more robust.
