@types/chroma-js: Generic type 'Scale<OutType, Color>' requires 2 type argument(s).

I tried using @types/chroma-js v1.3.0 with typescript v2.2.0 and v2.3.0 and both crash while compiling with this output:

ERROR in /usr/local/var/www/projects/ztrim/node_modules/@types/chroma-js/index.d.ts (290,29): ',' expected.

ERROR in /usr/local/var/www/projects/ztrim/node_modules/@types/chroma-js/index.d.ts (202,66): Generic type 'Scale<OutType, Color>' requires 2 type argument(s).

...

ERROR in /usr/local/var/www/projects/ztrim/node_modules/@types/chroma-js/index.d.ts (352,18): Generic type 'Scale<OutType, Color>' requires 2 type argument(s).

Anyone to confirm ?

I can confirm this is also happening to me; chroma-js@1.3.4, @types/chroma-js@1.3.0.

Taking a look now.

Works with typescript@2.3.4 -- and should work back as far as 2.3; the 'comma expected' is due to the default generic, which was added in 2.3 (see microsoft/TypeScript#2175).

@ruffiem are you sure that, when you tried with Typescript 2.3.0, your build system was genuinely using it?

[ruffiem]

Actually, it was bugged on TypeScript 2.3.2 but not 2.3.4 👍
