How to Iterate Over a Set in TypeScript


How to Iterate Over a Set in TypeScript ?

Answer

To iterate over a set in TypeScript, you can use the `forEach` method or a `for...of` loop.



✐ Examples

1 Iterate Over Set Using forEach Method

In this example,

  1. We define a set named `mySet` containing elements of a specific type.
  2. We use the `forEach` method to iterate over the set.
  3. Within the `forEach` method, we provide a callback function that takes each element as a parameter.
  4. Finally, we execute the `forEach` method and process each item in the set.

TypeScript Program

// Define set
const mySet: Set<string> = new Set(['apple', 'banana', 'orange']);

// Iterate over set using forEach method
mySet.forEach((item: string) => {
    console.log(item);
});

Output

apple
banana
orange

2 Iterate Over Set Using for...of Loop

In this example,

  1. We define a set named `mySet` containing elements of a specific type.
  2. We use a `for...of` loop to iterate over the set.
  3. Within the loop, we use the `of` keyword to access each element of the set.
  4. Finally, we execute the loop and process each item in the set.

TypeScript Program

// Define set
const mySet: Set<string> = new Set(['apple', 'banana', 'orange']);

// Iterate over set using for...of loop
for (const item of mySet) {
    console.log(item);
}

Output

apple
banana
orange
