could one please tell me about +c? Seems it converts string to int!

Approved

• You forgot to add it to assertion messages of fixed tests

• Also, missing return {r: 0, g: 0, b: 0} in initial solution setup

Quotes added.

I disagree with that, users should know that the given input is a string upon their code fails, hence the message should be wrapped in quotes (refer to example tests which also use quotes)

• hex is the input string, so JSON.stringify would just put quotes around it.
• fixed. Apparently the older version of TS was removed in the last couple of months.

• The assertion messages and random test's it block should be JSON.stringify(hex) instead of just hex

• Also, please update to TS 4.9 as it currently says invalid version

I did not change that part of the translation from jdold07, I merely made the return types more specific.

I personally never used lodash much, so I don't know what functions and constants it makes available from the top of my head.
I suspect the same for jdold07.

Is there a reason you have rolled your own randInt rather than import {random} from 'lodash'?

Made return type of solution setup and sample solution more specific.

as usually. it's difficult to make intresting task, so people trying to make more mysterious task, but as was mentioned in other Kata, trying to understand what people really want you to do, is part of the job) so from that perspective good kata) remember 7 red lines)

I agree. True OOP work.

Sample tests are wrong, change Test.assertEquals for assert.strictEqual to fix them.
