Switching Between States: Enums are commonly used in switch-case statements to execute different blocks of code based on the value of an enum variable. This usage is especially helpful when dealing with different states or options within a program. APIs and Interfaces: Enums are useful while de...
String-based enums, just like object literals, support computed names with the use of the square bracket notation, and this is usually not the case for number-based enums. Therefore, this limits our ability to use number-based enums in JSON objects, as it is usually not possible to compu...
