Too Long; Didn't Read
This is a list of tools I use when I develop websites, logos and anything else when I'm making content for the web. ColorPicker can color "pick" any color on your screen and get the HEX code. RunJS is a simple program that allows you to tinker with JS without the need to set up a full blown coding environment. VS Code is the only choice you should consider, with robust plugin support and cross platform support. Animista is versatile, fast and easy to pick up.
