Welcome to the wonderful world of JavaScript development! I hope you find it enjoyable and rewarding.
The basic tools of the JS trade these days are:
node, which runs JavaScript code.nvm (Node Version Manager), which updates node and lets you switch between different versions.yarn, a package manager for installing projects' dependencies.
