💻 Code
// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set/difference$0
const odds = new Set ( [ 1 , 3 , 5 , 7 , 9 ] ) ;
const squares = new Set ( [ 1 , 4 , 9 ] ) ;
console . log ( odds . difference ( squares ) ) ; // Set(3) { 3, 5, 7 } 🙁 Actual behavior
Property 'difference' does not exist on type 'Set<number>' . ts ( 2339 ) TypeScript does not recognize the property.
🙂 Expected behavior
I expected TypeScript to recognize the property, since:
MDN confirms it is widely available
Add types for stage 3 "set methods" proposal #57228 add types for set methods proposal #57230
Why is the compiler still showing that it isn't recognized?
