Does TypeScript have an equivalent of ES6 "Sets"

This worked for me.

One of the issues appears to be that typescript trys to use

ERROR TypeError: (intermediate value).slice is not a function

instead of Array.from();

in any event this code worked for me in my Angular 4 applicaiton

Array.from(new Set(Array)).sort(this.compareNumbers)

hope this helps someone

javascript typescript ecmascript-6 set

No. If you compile to ES5 or older Typescript only adds the syntactic changes from ES6. It doesn't add any of the standard library objects.

If you want those I suggest you look into something like core.js

javascript typescript ecmascript-6 set

You can use this type script library. Or maybe create your one set class using reference from this library
