I have used TypeScript for almost 2 years in this job.
I solved a problem today in leetcode with javascript, I found I did not know a very basic use of javascript, new function() { … }.
Usually I use class {constructor() {}} for it.
This is frustrating.

Should I use Python, which I have 3 year experience but not used for 2 years, or should I use javascript for interview?
Typescript is more cumbersome than JS.
