How to useMap in Javascript
In this approach, We are using a Map data structure where keys are enum values, and values are their string representations.
Syntax:
const enumMap = new Map([
[ENUM.VALUE1, 'String1'],
[ENUM.VALUE2, 'String2'],
// ... other enum mappings
]);
const stringValue = enumMap.get(enumValue);
Example: In this example, we have used the Map data structure to establish a direct mapping between enum values and their corresponding string representations.
Javascript
const OPERATION = { ADD: 'Addition' , SUBTRACT: 'Subtraction' , }; const operationMap = new Map([ [OPERATION.ADD, 'Addition' ], [OPERATION.SUBTRACT, 'Subtraction' ], ]); const currentOperation = OPERATION.ADD; const operationString = operationMap.get(currentOperation); console.log(operationString); |

Convert a JavaScript Enum to a String
Enums in JavaScript are used to represent a fixed set of named values. In JavaScript, Enumerations or Enums are used to represent a fixed set of named values. However, Enums are not native to JavaScript, so they are usually implemented using objects or frozen arrays. In this article, we are going to explore various approaches to converting a JavaScript enum to a string representation.
These are the following ways to convert an enum to a string:
