That's fine if you're talking about languages you use infrequently, but if you can't declare and populate an associative array in the main language you're interviewing in you shouldn't be surprised if your interviewer fails you.
Honestly, once a person has demonstrated some proficiency in a cross section of languages, you should just skip the language proficiency section and instead talk about how learning new languages has gone in the past. Look for any red flags or biases that are going to be a hindrance in the new languages particular paradigm, but otherwise the “can you X” is already a done deal.
What if I can google how to do that in all of the languages I've used (and many I haven't) faster than most can write it out from memory? How do I convey that to you and what is it worth to you?
Wrote memorization like that is one of my weaknesses but I can compensate for it. I heard an interesting theory that one aspect of intelligence is how efficiently you can forget information that you don't benefit from retaining. If our brains have finite storage capacity that seems pretty logical.
I'm smarter than what I thought :-)
& frequently forget how to iterate through arrays and objects in Typescript although been using it for years

Sounds fine with me, or via an IDE, or pseudocode
