Defines a user-defined enumeration(also known as an enumerated type or enum). An enum is made up of a list of strongly typed, named constants called members. The value of a variable defined as an enum is restricted to the list of members defined for that enum. Is there enum in JavaScript?
Now, let us understand a key feature why we use enums in the first place. It is a known fact as we have introduced about enums provided by Python, but it is noteworthy that two enum members can hold same values but the other way round is not possible – an enum member cannot hold ...
EnumMap: EnumMap is a specialized implementation of the Map interface that is used with enum keys. It offers high performance and type safety when working with enums as keys, thus providing efficient storage and retrieval. Benefits of HashMaps in Java Some of the benefits that HashMaps offer...
Now let us see how yield is used to return undefined function* bar() { yield; } let b = bar(); console.log(b.next()); You will get the output as shown below: { value: undefined, done: false } Do check out our blog onFive Types Of Errors In JavaScript – Method, Messages &...
Enums Parameter propertiesin class constructors. Namespaces Future JavaScript that is compiled to current JavaScript One considerable benefit of type stripping is that it does not need any configuration (viatsconfig.jsonor other means) because it’s so simple. That makes platforms that use it more...

When used together, "keyof typeof" can be used to get the property names of an object in TypeScript, where: "typeof" operator works on a JavaScript value (such as a variable, constant, parameter, function, class declaration, or enum) to infer the type of the value, and; "keyof" ...
This section describes 'enum' types, which are defined by 'enum' declaration statements. An 'enum' type is actually a special kind of class type.
If enums didn't exist, you might use a#define(in C) orconstin C++/C# to specify these values. Eg Too Many Ints to Count! The problem with this is that there are many moreintsthan colors. If violet has the value 7, and theprogramassigns a value of 15 to a variable then it is...
