How to use a custom conversion function In Typescript
We can define a custom function that iterates over the Set and manually adds each element to an array.
Example: In this example we defines a function setToArray to convert a Set to an Array by iterating over the Set and pushing its elements into an array. It then demonstrates this conversion with logging.
// Define a function to convert a Set to an Array
function setToArray<T>(set: Set<T>): T[] {
const array: T[] = [];
set.forEach(value => array.push(value));
return array;
}
// Define a Set
const testSet = new Set<number>();
for (let i = 1; i <= 5; i++) {
testSet.add(i);
}
console.log("Set:", testSet);
// Convert Set to Array using the custom function
const arrayFromSet: number[] = setToArray(testSet);
console.log("Array from Set:", arrayFromSet);
Output:
"Set:", Set (5) {1, 2, 3, 4, 5}
"Array from Set:", [1, 2, 3, 4, 5]
How to Convert a Set to an Array in TypeScript ?
A Set in TypeScript is used to create a particular type of list that does not contain duplicate elements. If any element is repeated more than once it will automatically remove the duplicate existence and consider it only once in the list. In this article, we will convert these types of lists into arrays that accept duplicate values as well.
These are the following methods to convert a set to an Array:
Table of Content
- Using the Array.from() method
- Using the spread operator
- Using the forEach() iterator method
- Using a custom conversion function
- Using the Array.concat() Method
