One of the most effective methods of transforming Enum to Set in TypeScript is by using a simple loop. Here's an example:
enum Fruit {
Apple = 1,
Banana = 2,
Orange = 3
}
const fruitSet = new Set<Fruit>();
for (const key in Fruit) {
const val = Fruit[key];
if (typeof val === 'number') {
fruitSet.add(val);
}
}
console.log(fruitSet); // Set { 1, 2, 3 }
In this example, we declare an Enum called Fruit
with three values. We then create a new Set
called fruitSet
and use a for loop to iterate over the keys of the Fruit
Enum. We check if the value is a number and if it is, we add it to the fruitSet
. After the loop completes, we log the fruitSet
to the console, which outputs: Set { 1, 2, 3 }
.
