In plain English

Coc.nvim is a plugin for the Vim and Neovim text editors that adds the kind of smart code features normally found only in full IDEs like Visual Studio Code. Vim is a powerful, keyboard-driven text editor beloved by developers, but by default it has no awareness of programming language semantics, it does not auto-complete based on available functions, highlight errors, or let you jump to a function's definition. Coc.nvim solves this by running a separate Node.js process alongside your editor that communicates with language servers via the Language Server Protocol (LSP). A language server is a background process that understands a specific programming language, it knows the syntax, can find references, suggest completions, detect type errors, and more. Because LSP is a standard protocol, the same language servers that power VS Code also work with coc.nvim. In practical terms, once installed you get features like intelligent autocomplete as you type, inline error and warning indicators, go-to-definition, find-references, code formatting, and one-click fixes, all inside Vim. You install language-specific support as coc extensions (for example, coc-tsserver for TypeScript). It requires Vim 9.0 or Neovim 0.8 and Node.js 20 or newer, and is written in TypeScript.
