Both methods above show how to make enums powerful by extending their functionality. Though it is impossible to directly extend anenum, we can use these tricks to extend their functionalities. Enjoying our tutorials? Subscribe to DelftStack on YouTube to support us in creating more high-quality...

Enumeration is the ordered listing of all items in a collection. In Python we can use this with a list or tuple to (data collection objects) into an enumerate object. The enumerate object has a name and value for each enum member within the object. The enumerate object can be updated (...
In making progressed Enum types in Typescript, we utilized Typescript’s convenient read-only and private access modifiers to make an enum design with impressive adaptability and progressed highlights. The following sensible advance is to structure an equal example for enums in Javascript — for sit...

Enums are not natively supported in JavaScript, however, Object.freeze can be used to imitate their functionality. This is because TypeScript treats enums as if they were real objects at runtime, even non-const enums. We can use this construct as shown in the example below: const direction...
Interfaces in TypeScript are a powerful way to represent type structures. They allow you to make the usage of those structures type-safe and document them simultaneously, directly improving the developer experience. In this tutorial, you will create interfaces in TypeScript, learn how to use them...
If you’re using a data cache locally, make sure to clean that cache or use an aging mechanism to avoid large chunks of data being stored that you’re unlikely to reuse Functions Next, let’s look at functions. As we’ve already said, garbage collection works by reclaiming blocks of mem...
