Enums in TypeScript enable mapping short lists of values into numbers, facilitating comparisons.
Different approaches for iterating over enums in TypeScript are explored in this article.
Numeric Enums map keys to numeric values and can be iterated using Object.keys() and Object.entries().
String Enums map keys to string values and are best iterated using Object.values().
Object methods like Object.keys() and Object.values() can be used to iterate over enums.
Iterating over enum values using for loops is another approach, allowing reverse mapping in numeric enums.
By converting an enum to a typed array, strict typing of enum keys can be preserved for iteration.
Lodash utility method forIn() can also be used to iterate over enums in TypeScript, providing flexibility in filtering keys.
A reusable utility function getEnumKeys() is introduced for consistent enum key extraction across codebases.
Multiple techniques for iterating over enums in TypeScript are discussed, emphasizing the importance of choosing the right method based on requirements.
