High-level programming language
I started using Javascript in my NFT Market I was making in May of 2021. I've used it previously, but I didn't use much of it. I'm far from fluent with the language, but I figured if I can learn C and Python and have used Java Script, I believe I'm allowed to put it down as a skill. I think JavaScript isn't too complex of a language to learn, and if I had a whole week to study the docs and the syntax, I could be effective with the language. Out of all my skills, Java Script is the skill I have used the least as of July 17, 2021.
For my projects, the only times I've used Java Script with purpose would be my ERC20 ICO Crowdsale and the NFT Market I am making, and a little with the website that you are looking at right now. I have used the JavaScript libraries Mocha for testing my smart contracts. Soon I would like to learn Angular or React, most likely would choose to React as it is the talk of the town lately.
