how to get the difference of two sets in typescript

To get the difference of two sets in TypeScript, you can convert each set to an array and then use the spread operator to filter out common elements.

Here's an example:

index.ts
const set1 = new Set([1, 2, 3]);
const set2 = new Set([2, 3, 4]);

const difference = [...set1].filter(x => !set2.has(x));

console.log(difference); // [1]
156 chars
7 lines

In this example, we create two sets (set1 and set2) with some overlapping elements. We then use the spread operator (...set1) to convert set1 to an array, and use the filter method along with the has method to filter out the elements that exist in set2.

The resulting difference array contains only the elements that are unique to set1. In this case, the difference is [1].
